§Handling of returned goods
§Waste disposal
·Distinguish: physical flow and information flow
oOrderàconfirmationàannouncementàreply (EDI)
·
Peculiarities: transport system elements
·Fixed and mobile capital (infrastructure and transport means)
oCapital intensive
oLimited alternative use
oEconomies of scale
oMonopoly/competition
oDedication/own transport
Peculiarities: Transport
·Complex structure of transport services
·Derived demand
·Unevenly spread over time
·Non-storable
Cost contributions of logs components in 2013
·Transport 59.8%, invent carrying costs13.5%, warehousing 14.3%, management/admin 12.5%
Choice: Transport modes
·Decide on the best choice of modes or a combination, structuring the transport system in such a way that good logs coordination takes place
·Criteria:
oSpeed
oFlexibility
oReliability
oReachability and connectedness
oEase of use
oInformation
o Image
·Modes of transport:
oDeep sea fishing
oShort sea fishing
oRail
oInland shipping
oRoad
oAir
oPipeline
Distribution decisions
·Look at consolidation (place a warehouse close by and send smaller units from different plants to the final place)
·Break bulk (break up a large volume of goods into smaller volumes and send them out individually)
·Mixing is using consolidation and break bulk in a combination
SA Economic growth
·SA’s economic activity is highly skewed
·Some economic centres found inland are bigger than those located near ports
·Contradicts theory
·
oSA problem – density – markets far away and gauteng far for ports
oTONKM = transport of 1 ton goods over 1km
oTo keep SA’s economy going the distribution of 348 billion tonkm needed
oCorridor transport – long distance movement between industrial centers
oPrimary transport – export of mining commodities (far from ports)
oRural transport – low density movement in rural areas
oMetropolitan transport – urban movement in big industrial areas
oSA’s long distance corridors Cape – Gauteng and Durban to Gauteng makes it difficult
oLow value mining commodities and agricultural products transported over long distances. Due to high transport costs the price /costs of these commodities increase
o1% reduction in log costs can save SA R3.39 billion per annum
·SA’s geographical position places it at a disadvantage in terms of distance from its four largest partners
oUK, Europe, USA and Japan
·Many of the regions against who SA competes are on average closer to these markets
oSouth East Asia, Eastern Europe, South America and Australia
·Majority of SA’s manufactured goods are produced in Gauteng
·Lack of well thought-out freight logs strategy
AN overview of SA’s Trade
·Bulk exports represent the main cargo carried by SA maritime SC in terms of volume
o75.4 million tons of coal through the Port of Richards Bay in2015
o59 million tons of iron ore through the Port Saldanha exported in 2015
·Most of the bulk commodities exported from SA are made up of raw materials
oCoal, iron ore, manganese ore and other ores and minerals
·Rail is used for the inland transport leg
·SA’s marine links are currently provided by foreigners
·Bulk products from SA are usually sold F.O.B
·Liner trades – world trend is for shipping companies to integrate port and overland links into their services – in order for SA to compete internationally, their container SC will need to follow the trend
·SA container market moved 4.83 millions TEUs in 2014à accounts for less than 1% of global container trade
·SA’s container trade
o42% imports, 41%exports, 17% transhipments
·At present, most of the containers are being transported inland in SA by road transport
·Up until road transport was deregulated, rail transport was protected from competition and Transnet was the main domestic carrier of containers
·Since deregulation, the modal split has changed in favour of road transport
·Up until 1998, Transnet controlled all the containers from the ports and no other haulers were allowed to transport containers within a defined radius
·Since 1998 there has been an open gates policy
·Africa accounts for just 2.4% of world GDP, but hosts 15% of its population
·GDP is one of the most developed and economically stable countries on the African continent
·Trade plays an important role in reversing poverty
Strengthen Relationships with Neighbours
·Southern African Railway network was built under different conditions than those that exist today
oHistorical and political incidents
·Africa contains 15 landlocked countries
·Distance to the sea ranges from
o220km (Swaziland) and 1735km (Chad)
·Efficient corridors required for international trade
·Infrastructure
·High permissible axle loads for road transport
·The transport network outside SA operates below its original design capacity
·Being landlockedà geographical disadvantage
·Low density and poor quality of infrastructure
oLandlocked countries
oCoastal countries
Benefits of cross border movements
·SA’s economy can benefit from cross border movements
·Brings foreign revenue into the country
oProvides – increase profit
oWorkers – increased salary
oCustomers – goods they would otherwise not be able to get or goods at lower prices
oGov – benefit indirectly from increased tax revenue that is generated from higher levels of economic activity or directly by using some of the revenue earned to pay for other national objectives or invest in other essential infrastructure
·Striving to reduce transport and logs costs for both economic and political reasons
·A reduction in transport and logistics costs will allow SADC countries to compete globally
Strategies developed with regards to transport and logistics
·The demand for land transport in the SA economy is increasing
·The majority of growth is being captured by the road sector
·Change in the long-haul road/rail relationship in order to avoid road gridlock
·The lack of consideration for the infrastructure component of road costs vs rail costs is highlighted by the exponential rise is SA’s truck fleet
Establish SA as a regional hub
·The efficient transportation of goods in international trade is vital for the economic welfare of a country
·Efficient ports are directly proportional to national economic activity
·African ports have some of the highest logs costs per TEU in the world
·The situation is made worse by insufficient infrastructure
·With the exception of Mauritius, SA has the lowest costs in Africa and is the most accessible via most trade routes
·Shipping trends indicate that shipping lines are striving to hub ports
·Several countries and terminal operators in Sub-Saharan Africa are developing hub capacity
oDeveloping south-south trades
oChanging trade route dynamics
oGrowing regional volumes
·SA is relatively isolated from the major East/West trades
·It is an end port that serves the North/South trade route and acts as a gateway for South Africa and Sub-Saharan Africa
·SA can play a major role in the container trade
·This coud generate additona economic activity and employment opportunities, stimulate growth and increase national trade competitiveness through economies of scale, scope and density
·ThePort of Coega (Ngqura)
oAccommodate ships up to 12 500 TEUs
·Expansions and upgrades at the Ports of Durban and CT will also help establish SA as a regional hub
Road and Rail Problems
·Since the deregulation of road transport, rail transport in SA has experienced a serious decline in the market share
·Rail transport – over longer distances economies of scale can be realised
·Rail transport at a disadvantage to the door-to-door service pf road transport
·In international settings, long-haul rail costs are generally 70% of those of road transport, whereas in SA rail and road freight have similar costs
·Transnet must overcome the perception that companies have of rail transport in SA
·Service levels still not meeting necessary levels of efficiency
·Rail transport > 500km
·Freight is still moving long distances to ports by road transport
·Lack of modal collaboration
·Transport productivity is another problem facing SA’s freight transport system
oCongestion of SA’s roads
oLack of sufficient transport and infrastructure
oLack of vehicle scheduling and route planning
oLack of drivers’ skills and poor management and administration
·Overuse of the national and urban road network
·Overloading on SA roads
Cross Border Agreements
·SA has 52 noteworthy border posts
·60% of traffic is handed through the 5 biggest border posts
oLebombo, Beitbridge, Oshoek, Nakop and Maseru Bridge
·Obstacles to the smooth movement of freight at border posts include:
oInexperienced staff
oA lack of necessary equipment
§Manual clearing takes twice as long, but the systems required in order to assist the electronic clearing not fully operation yet
Specific constraints addressed through public investments are reorganisation
·Lack of conformity between countries
·High degrees of complexity
·Extraordinary levels of delays
·The amount of paperwork required for moving goods between SADC countries causes delays
·As does the requirement pf 2 stops at most border posts and non-standard gross vehicle mass requirements
·Lack of sharing of info between firms
Public initiatives: cross-border movements
·Southern African states are fragmented in terms of transit procedures and standards
oCustomers procedures, transit charges, society checks, training, road design standards and documentation
·Lack of political commitment towards the effective integration of transport issues in the strategies of poverty reduction
·Long and inappropriate documentation procedures
·Corruption
·High transit costs including insurance
Challenges remaining and current efforts
·The reliability, speed, flexibility and responsiveness of the freight transport system in SSA is an obstacle to being internationally competitive
·Divide the national freight system into different stages
·Core structural issues in the freight transport system have been ignored up till now
·Not feasible to provide the infrastructure that will be required by the economy over the next 20 years in the same rail/road configuration that is currently available
·Important to implement intermodal corridors

§Other causes not within control of the carrier
oImportant to consider when selecting a carrier
oCustomer service
oProtective packaging
Single Service choices
·Rail
·Truck
·Air
·Water
·Pipeline
Intermodal transport
·Logistically linked movement using two or more modes of transport on the line-haul part of the route
oReason intermodal transport is to benefit from the advantages of the different modes of transport
oCan overcome disadvantages of one mode of transport by supplementing it with another mode
·Trailer-on-flatcar
·Container-on-flatcar
Agents and small shipment services
·Agents – offer transport services to shippers but own little or no line-haul equipment
oHandle numerous small shipments and consolidate them into vehicle load quantities
oCompetitive rates
oPickup and delivery services

oSize of transport equipment
oDifferent geographic territories
oForeign trade zone
oCustomers’ expenses, tariffs, duties and taxes
oForeign trade zones or free ports – duty free areas established at one or more entry points within a country, such as seaports and airports, where foreign goods may enter, be held or processed in some way and be reshipped without incurring duties
·Foreign (Free) Trade Zone
o
·Advantages of foreign (free) trade zones
oImported goods may be left at trade zones for storage, manipulation to change custom classification, assembly, exhibition, grading, cleaning, selling, mixing with foreign and domestic merchandise, repacking, destruction, sorting and other services and then shipped out of the zone to another country without customs formalities or control
oForeign govs pay duties on goods in the trade zone only when they enter the customer’s territory of the importing country
oImported goods that are improperly marked for entry into the domestic market can be remarked at the trade zones, thus avoiding fines on the goods
oGoods may be repacked into smaller or larger quantities
oGoods that undergo shrinkage to spoilage, evaporation or damage do not incur duties on the lost amount
oSavings can sometimes be realised through shipping goods unassembled to the zone and then assembling them
oThe capital tied up in duties and bonds can be released for more profitable uses when products using duty-subject foreign materials are shipped to the trade zones to remain until foreign buyers are found or are ready for delivery
oImporters may obtain privilege foreign trade statuses whereby duties are frozen against future increases
oManufacturing conducted in trade zones incurs duties only on the imported materials and component parts in the finished product entering into the domestic market
oTangible personal property is generally exempt from state and local taxes
oCustomers security requirements provide protection against theft
oMerchandise my remain in a zone indefinitely
·Bonded warehouse can serve as foreign trade zones
·Agencies and services
oThe number and variety of the middlemen or agents
§Customhouse brokers, international freight forwarders, export merchants, export agents, export commission houses, import commission houses, wholesalers, brokers, international departments of banks
oProvide more services than just transportation
oGetting shipments across borders
§Preparing paperwork for customs, coordinating customs inspections, shipment warehousing and consolidation, freight optimisation and shipment tracking
Transport cost characteristics
·Variable and fixed costs
oFC- do not vary with services or volume
§Roadway acquisition and maintenance, terminal facilities, transport equipment and carrier administration
oVC- vary with services or volume
§Line-haul costs (fuel and labour), equipment maintenance, handling/pickup and delivery
·Common or joint costs
oMany transport costs are indivisible
oBackhaul
Rail cost characteristics
·High FC and relatively low VC
·High terminal costs: un/loading, billing and collecting, yard switching of multiple product, multiple shipment trains
·FC: railway maintenance, depreciation and administration
·VC: wages, fuel, oil and maintenance
·Increased volumes result in economies of scale
·Longer distances result in economies of scale
Highway (Road) cost characteristics
·Contrasting with rail
·FC are lowest of any carrier
oMotor carriers do not own the roadway over which they operate
oTractor-trailer represents a small economic unit
oTerminal operations do not require expensive equipment
·VC costs are high
oHighway construction and maintenance costs are covered in forms of fuel taxes and tolls
·Terminal expenses
oPickup and delivery, platform handling/billing and collecting
·Line-haul expenses
o50-60% of total costs
·Trucking costs do decrease with shipment size and distance as terminal costs and other fixed expenses are spread over more ton-miles, but not as dramatically as rail costs
Water (Shipping) cost characteristics
·FC- transport equipment and to some extent terminal facilities in the form of terminal operations
oWaterways and ports are generally publicly owned
oCosts for un/loading cargo
oHigh stevedoring costs
·Low line-haul costs
oOperating transport equipment
·Significant economies of scale with volume and distance
·One of the cheapest forms of transport over long distances and in substantial volumes
Air cost characteristics
·Similar cost characteristics to water and highway carriers
·Airline companies do not own the airspace or air terminals
·Airlines p
·urchase airports services as needed in the form of fuel, storage, space rental and landing fees
·Ground handling and pickup and delivery make up terminal costs
·Airlines own or lease their own equipment – annual FC
·In the short run, airlines VC are influenced more by distance than shipment size
·Great inefficiency in take-off and landing, VC reduced by length of haul
·Volume indirectly influences VC
·Premium service especially over short distances
·Substantial cost reductions over long distances
Pipeline cost characteristics
·Very similar cost characteristics to rail transport
·Pipeline companies, or the oil companies that own the pipelines, own the pipe, terminals and pumping equipment
·Own or lease the right of way for the pipe
·Highest ratio of FC to total costs of any mode
·Must work on high volume to spread the high FC
·VC – power to move the product and costs associated with the operation of pumping stations
·Costs per ton-km decrease substantially if there is sufficient throughput to justify a larger pipe
Rate Profiles (NB)
·Prices that for-hire carriers charge for their services
·The most common rate structures are related to volume, distance and demand
·Volume-related rates
oCosts of services are related to shipment size
oShipments of high volumes are transported at lower rates than small shipments
oRates may be reflected in the rate structure in several ways
§Rates may be quoted on the volume shipped
·Small shipments (min charge)
·Larger shipments (charged LTL)
·Large shipments- truck loads (vehicle load rate)
§High volume can be considered justification for quoting a shipper special rates on particular commodities
·Distance-related rates
oRange from being completely invariant with distance to varying directly with distance, with most structures lying between the two extremes
·Uniform rates
oOne transport rate for all origin-to-destination distances
oPostage
·Proportional rates
oFor carriers with significant line-haul cost components
oBy knowing only two rates, one can determine all the rates for a commodity by straight line extrapolation
oFavours short haul shipper
oTerminal charges are not covered on the short haul
oTruck loads can have this characteristic, because handling costs are minimal
·Tapering rates
oBuilt on the tapering principle
oCosts will show rates increasing with distance, but at a decreasing rate
oThe taper will depend on the level of fixed costs that the carrier has and the extent of the economies of scale in line-haul operations
·Blanket rates
oSingle rates that cover a wide area at the origin, destination or both
oMost common for products being hauled over long distances and whose producers or markets are grouped in certain areas
oA form of rate discrimination, but the benefits of rate simplification for both the carriers and the shippers outweigh the disadvantages
·Demand-related rates
oValue of service
oThe rate cannot exceed an upper limit
oTwo dimensions determine the value of the service to the shipper
§The shippers own economic circumstances
§Available alternative transportation services
Line-Haul rates
·Charges incurred between origin and destination terminals, or door-to-door in the case of truckload services
·Special service charges are prices paid for additional services – terminal services, stop-off services
oBy product
oBy shipment size
oBy route
oMiscellaneous
·Line-Haul rates: By product
oIf an individual rate were quoted for each product item between all origin-destination point combinations for all transport services, an impractically large number of rates to be administered would resut
oA product classification system was devised
oA number of factors are taken into account in establishing a product rating. These include:
§Density
§Stowability
§Ease of handling
§Liability
·Line-Haul rates: Class rates
oLinked to freight classification
oOnce a product has a class rating, then the line-haul charges can be determined
oThe class rate is a function of the distance between shipment origin and destination points as well as other factors
§
§Break weight= weight above which the next higher weight break rate should be used for lower transport costs
§Ratenext= rate for next higher weight break
§Weightnext=minimum weight of next higher weight break
§Ratecurrent= rate for true weight of shipment
§Example
·
·
o200cwt. Times by 1 is what it is meant to be
·Line-Haul rates: Contract rates
oRates reflect a number of circumstances around an individual shipment or shipper
§Volume of the shipment
§Direction of the movement
§Overall value as a customer
oContract rates take precedence over the more general class rates
oMay be special, one-of-a-kind rates reflecting individual shipping situations
·Line-Haul rates: Freight-All-Kinds
oWhen carriers quote single rates for a shipment regardless of the classification of the commodities that make up the shipment
oOften used by freight forwarders
oFollow the costs of providing the transportation service rather than the value of the service
·Line-Haul rates: By shipment size
oRates differ based on the shipment size
oRailroads, truckers and transportation brokers usually have a lower quantity limit on which to base charges, or they will have a flat minimum charge so that actual charges cannot drop below this minimum
·Line-Haul rates: Other incentive rates
oIncentives to ship in large quantities
oIn-excess rate – lower than vehicle load rates and apply to only those quantities that exceed the vehicle load minimums
§Encourages shippers to increase shipment size and allows carriers to better utilise the capacity of their equipment
oSome carriers have established time-volume rates
§Reduced rates are offered if a minimum tonnage is moved within a specified period (coal)
·Line-Haul rates: By route
oWhen shipments involve full-vehicle-load movements, carriers use a per-km charge to calculate total shipping expenses
oWhen a vehicle is loaded with cargo destined for more than one stop, a stop-off charge may be added to the bill
oThe per-km rate is determined by the location of the last point on the route
o
·Line-Haul rates: Miscellaneous rates
oCube rates
§Average of many different product characteristics
§When articles are very light and bulky, class ratings do not fully compensate the carrier for the costs incurred for transporting these items so cubed rates are used
§Based on space occupied rather than weight
oImport or export rates
§To encourage foreign trade, special rates are charged on inland shipments originating from or destined for foreign points
§Lower rates than comparable shipments with origins and destinations inland
oDeferred rates
§At times, the shipper is willing to accept the possibility of increased delay in delivery compared with regular service in exchange for lower rates
§The shipper is promised that delivery will be made no later than a given date
§Carriers use such freight to fill up available space
oReleased value rates
§The carrier’s liability is limited to some fixed figure
§Released value rates are particularly useful when the actual value of the goods is difficult to estimate
oOcean freight rates
§Rates do not closely follow the classification schemes of domestic carriers
§Quoted on either a space or a weight basis
§Ocean carriers may belong to conferences
Special service charges
·Extra charges are made
·Special line-haul charges or terminal charges
·Special line-haul services
oDiversion and reconsignment
§Diversion – changing the destination of a shipment while en route
§Reconsignment – changing the consignee of a shipment, after it has reached its original destination
oTransit privileges
§Rail carriers and (to a lesser extent) motor carriers
§Treated as if moves from an origin to a destination
§Rate includes the rate from origin to destination plus a small charge for the stop
§Grain
§Stop-off privilege
·Example
o
o
·Special service charges: Special line-haul services
oProtection
§Require additional protection
§Perishable products, fragile products
oInterlining
§Not all carriers serve all regions
§One carrier may pick up a shipment and then give it to another carrier that serves the destination region
§The first carrier pays the second, but the shipper is billed by the first
§Rate must cover the profit of both carriers
·Special service charges: Terminal services
oPickup and delivery
§Some carriers do not provide pickup and delivery as part of their line-haul rates – offered as an additional charge
§When included, it is usually limited to the immediate surrounds
oSwitching
§The movement of railroad cars from private sidings and junctions to rail terminals or stations
§Similar to pickup and delivery but rail cars are involved
oDemurrage and detention
§Penalty charges imposed on the shipper or consignee for holding the carrier’s equipment beyond an allowed free time that the carrier may hold the shipment
§48 hours
Private carrier costing
·Provide a level of customer service that is not always obtainable from for-hire carriers
oService reliability
oShort order cycle times
oEmergency response capability
oImproved customer contact
·Achieving a lower cost than for-hire carriage
·Cost of operating privately controlled transport is determined much the same way as an asset
oFC – insurance on the vehicle, interest charges on the money tied up on the vehicle, licensing fees, equipment amortisation and expenses associated with housing the vehicles
oOperator costs – driver compensation
oVehicle operating costs – fuel, tyres and maintenance
Documentation
·Bill of lading
oThe key document on which freight moves
oA legal contract between the shipper and the carrier for the movement of designated freight with reasonable dispatch to a specified destination, arriving damage free
oIt serves as a receipt for goods, subject to the classifications and tariffs that were in effect on the date that the bill of lading was issued
oIt serves as a contract of carriage
oIt serves as a documentary of evidence of title
oStraight bill of lading – is a non-negotiable legal document
§Are consigned only to the specific person noted in the document
§Cannot be traded or sold
oOrder bill of lading – the goods are consigned to the order of the person
§May be traded or sold by endorsing the order to another person
§Allows the shipment to obtain payment for goods before they reach their destination by endorsing the order bill of lading over to a bank and receiving payment
·Freight bill
oMuch the same info as bill of lading – origin and destination, quantity shipped, product and the persons involved
oThe charges
oThe freight charges may be prepaid by the shipper or billed collect from the consignee
oPayments for rail service generally made in advance, except where credit is extended to financially responsible shippers
·Freight claims
oCarrier’s legal responsibilities as a common carrier
§A common carrier has the responsibility to move freight with ‘reasonable dispatch’ and without loss or damage
§Bill of lading defines the limits of carrier responsibility
§Losses due to unreasonable delay or failure to meet guaranteed schedules are recoverable to the extent of the value reduction resulting directly from the delay
oOvercharges
§Results from some form of incorrect invoicing
·Application of incorrect classification, failure to use the correct rates, use of incorrect distances, simple arithmetic errors, duplicate collection of freight charges, errors in determining item weights, and differences in interpretations of rules and tariffs
·Normal bill auditing may detect errors before payment is made and a corrected bill of lading may be issued
·Up to 3 years for overcharge claims
International transport documentation
·Exporting
oBill of lading – receipt for the cargo and a contract for transport between the shipper and carrier
oDock receipt – used to transfer accountability for cargo between domestic and international carriers
oDelivery instructions – provides specific instructions to the inland carrier regarding delivery of goods
oLetter of credit – financial document guaranteeing payment to the shipper for the cargo being transported
oConsular invoice – used to control and ID goods shipped to particular countries
oCommercial invoice – bill for the goods from the seller to the buyer
oCertificate of origin – used to assure the buying country precisely in which country the goods were produced
oInsurance certificate – assures the consignee that insurance is provided on the goods while in transit
oTransmittal letter – a list of the particulars of the shipment and a record of the documents being transmitted, together with instructions for disposition of the documents
·Importing
oArrival notice – informs as to the estimate arrival time of the shipment along with some details of the shipment
oCustoms entries – a number of documents describing the merchandise, its origin, and duties that aid in expediting clearance of the goods through customs, with or without the immediate payment of duties
oCarrier’s certificate and release order – certificates to customs the owner or consignee of the cargo
oDelivery order – issued by the consignee to the ocean carrier as authority to release the cargo to the inland carrier
oFreight release – evidence that the freight charges for the cargo have been paid
oSpecial customs invoice – an official form usually required by US customs if the rate of the duty is based upon the value, and the value of the shipment exceeds a fixed dollar amount

Need for a storage system
·In a perfect world where demand and supply were known at all times, storage wouldn’t be needed
·Storage improves supply and demand coordination, which helps to lower overall costs
Reasons for storage
1.Reduce transportation-production costs
2.Coordinate supply and demand
3.Assist in the production process (Production needs)
4.Assist in the marketing process (Marketing considerations)
Reduce transportation-production costs
·Transport is one of the biggest costs in a SC
·Warehousing and associated inventory are seen as added expenses
oHowever, traded off with lower costs realised from improved efficiency in transport and production
Coordination of supply and demand
·Highly seasonal production (availability of raw materials), along with reasonably constant demand results in problems in coordinating supply and demand
·Stockpiles needed to be created when the raw materials are available
oEnabling the firm to create the product even when they are scarce
·Firms with uncertain demand, produce at a constant level throughout the year to minimise production costs and build inventories to meet the demand
·Costs of raw materials also influence the amount that is purchased
oWhen the prices are low, firms may purchase quantities in advance
Production needs
·Warehousing is part of the production process
·Manufacturing of certain goods requires time for them to age (cheese, wines)
oWarehouses hold them in this time
oProducts are taxed
oBonded warehouses allow for the tax to be deferred
§Only pay the tax when the good is sold
·In some cases, the warehouse may perform some value-added services in addition to holding the inventory
oPacking, private labelling, custom product preparation
Marketing considerations
·Concerned with how readily the product is available to the marketplace
·Warehousing is used to put value into a product
oWarehousing a product close to customers:
§Reduces delivery time
§Supply made readily available
§Improved customer service through faster deliveryàincreased sales
·People want instant gratification
Storage system functions
1.Inventory holdings (storage)
a.Accumulation of inventory overtime
2.Materials handling
a.Loading and unloading
b.Moving products to and from
c.Order picking
Storage functions
1.Holding
a.Provide protection and orderly holding of inventories
b.Length of time for holding goods and requirements of storage, determine facility layout
i.LT specialised storage (wines), general purpose merchandise, temporary holding
c.Can be finished goods, semi-manufactured goods or raw materials
2.Consolidation
a.Transportation rate structures, rate breaks, influence use of storage facilities
b.Goods originate from a number of sources, could be economical to have a collection point
i.Consolidates small shipments into one large shipmentàreduce transport costs
c.Cross docks: goods are transferred directly from inbound to outbound docks with little to no storage
3.Break-bulk
a.One large shipment is broken up into smaller shipments
b.Common in distribution or terminal warehouses
4.Mixing
a.Orders are consolidated but at the same time break-bulk is applied
b.Three trucks come into the warehouse carrying one type of good each
i.Two trucks leave the warehouse carrying three types of goods each
Materials handling functions
1.Loading and unloading
a.First and last activity in the material handling events chain
b.Unloading and movement to storage are often one operation
c.Sometimes they are to operations as the goods are first sorted, inspected and classified before moving to storage
d.Loading- final check of order content and order sequence
i.Additional effort to prevent damage (bracing and packing the load)
2.Movement to and from storage
a.Between loading and unloading, goods may be moved several times
b.Movement equipment can vary from manual push trucks/carts to fully automated and computerised stacking and retrieval systems
3.Order filling or picking
a.Selection of stock from storage areas according to sales orders
b.Often most critical materials handling activity
i.Labour intensive and relatively more expensive than other materials handling acts
Storage Alternatives
1.Ownership
2.Rental
3.Lease
4.Store in transit
Ownership
·Most manufacturing firms and services orgs own storage space in some form
oBack room office for supplies, finished goods warehouse
·Advantages of owning the space:
oLess expensive warehousing (especially if there is high utilisation)
oHigher degree of control over warehousing operations (efficient warehousing, high service)
oProducts require specialised personnel and/or equipment, only feasible option
oBenefits accrue from real estate ownership
oSpace can be converted to other uses at a future time
oMulti-purpose (sales office, purchasing department, private truck fleet)
·Better control, lower costs, increased flexibility
Rental
·Can be public warehouses or 3PL’s or freight forwarders
·Provide the same services as in private
·Types of warehouses
oCommodity- limit services to storing and handling (lumber cotton, tobacco, grain)
oBulk storage- storage, handling, mix products and break bulk (oil, highway salts, syrups)
oTemperature controlled- control the storage environment temp and humidity (perishables)
oHousehold goods- storage and handling (moving companies are main users)
oGeneral merchandise- most common type, don’t require special services
oMini warehouses- 20-200 square feet, often grouped together, extra space, security is a problem, attraction is convenient locations
·Inherent advantages
oNo fixed investment
oLower costs when low utilisation
oLocation flexibility (ST arranges for rental) (easy and inexpensive to change warehouses)
·Services
oHandling, storage and distribution
oTraffic info, physical inventories, dunnage and bracing
oModern data facilities, fumigation, freight consolidation plan
oLoading and unloading, yard storage
oDry bulk commodity handling storage and bagging
·Bonding arrangements are made with the gov for certain goods (tobacco and liquors)
oTaxes/duties are levied
oGoods cannot be moved from bonded warehouse unless to another bonded warehouse until the required taxes are paid
oOwner of goods benefits by having more capital as tax is paid once good is sold
·Documentation and legal considerations
oWarehouse receipt
§ID what is being stored, where being stored, who owns the goods, whom being delivered to and the t’s and c’s of the storage contract
§Can be negotiable or non-negotiable
·Non-negotiable- goods cannot pass to another person without written instructions
oBill of lading
§Contract document used in the movement of goods
§Spells out the t’s and c’s under which a carrier moves goods
oOver, short and damage report
§Issued upon receipt of goods at the warehouse
oInventory status report
§Shows item, quantity and weight of goods at the end of the month
Leased space
·Represents an intermediate choice between ST space rental in public warehouse and LT commitment of a private warehouse
·Lower rate may be obtained from the space owner
·Can come from space from manufacturers who are not fully utilising private warehouse, 3PL’s
Storage in transit
·When goods remain in transportation equipment during delivery
·Special form of warehousing that requires coordination with choice of transport
oDifferent choice means different transit times
Materials handling considerations
1.Loading unitisation
2.Space layout
3.Storage equipment choice
4.Movement equipment choice
Loading unitisation
·As load size increases, fewer trips required to store a given quantity of goods= greater economy
·Number of trips is directly related labour time necessary to move goods
·Consolidate small packages into one load
·Palletisation
oPortable platform, on which goods are stacked for transport and storage
oPermit the use of standardised mechanical materials handling equipment to handle a wide variety of goods
oAids in load unitisation and increases space utilisation (more stable stacking/higher stacks)
oPallet size and configuration depend on size, shape, weight and crushability of gods as well as the materials handling equipment capacity
·Containerisation
oIdeal in load unitisation and materials handling system compatibility is the container
oLarge boxes in which goods are stored and transported
oWaterproofed and locked, storage can occur in an open yard
oStandardised materials handling equipment can be used to move them and they are interchangeable among different transportation modes
Space layout
·Location of stock in the warehouse directly affects the total materials-handling expense of all goods moving through the warehouse
·Balance between materials handling costs and space utilisation is sought
·Layout for storage
oLow turnover, primary concern is to configure the warehouse for storage
§Storage bays (wide and deep), stacking as ceiling height or as high as load stability permits
§Aisles narrow
§Assumes extra time required for moving stock in and out of storage areas is more than compensated for full space utilisation
oTurnover increases
§ Aisles are wider and stack height is decreased
§Reduce time spent placing and retrieving stock
·Layout for order picking
oSequencing
oZoning
oBatching
Storage equipment choice
·Important storage aid is the rack (shelves on which goods are placed)
·Racks promote floor to ceiling stacking, items with high turnover should be placed at the bottom
·Racks also aid in rotating stock
·Other aids are shelf boxes, horizontal and vertical dunnage, bins, and U-Frames
Movement equipment choice
1.Manual equipment
a.Hand operated equipment
b.Provide some mechanical advantage in movement of goods and requires only a modest investment
c.This equipment is often used for special use (carpet handling, furniture and pipe handling)
d.Flexibility and low cost often make it a good choice when product mix in the warehouse is dynamic, volume flowing through is not high
2.Power-assisted equipment
a.Increases output per worker per hour
b.Cranes, industrial trucks, elevators and hoists but most importantly the forklift
c.Modest investment which makes it a popular system
3.Fully mechanised equipment
a.Bar-coding, scanning tech, computer controlled handling equipment
b.Automated storage and retrieval systems
Storage system costs and rates
·A firm pays storage system costs either through rates charged by an outside firm offering such services or through internal costs generated from the particular materials handling system
·4 systems
1.Public warehousing
2.Leased warehousing, manual handling
3.Private warehousing, pallet and forklift truck handling
4.Private warehousing, automated handling
Public warehousing
·Rates are negotiated between the warehouseman and the customer
·Rate will be based upon volume, time, different items, special requirements, ave outbound size
·Costs are grouped into three categories: storage, handling, accessorial costs
Leased warehousing, manual handling
·Leasing is a LT commitment, the charges are incurred at regular intervals, unlike public, and so can be treated as a variable cost
·Handling equipment requires a modest investment if the equipment is company owned
·Labour costs are substantial
Private warehousing, pallet and forklift truck handling
·Commonly chosen alternative to public
·All costs are internal, provided equipment is not leased/rented, major fixed cost to firm
·Low variable costs, thus substantial volume needs to be used to make this an economical option
Private warehousing, automated handling
·Extremely high fixed costs and tiny VC
Virtual warehousing
·A company does not have a warehouse of items own but it has other companies which it gets its supplies from and they keep inventory for them
·Think of Dell and how they build personalised computers but don’t keep stock themselves
Modes of transport: maritime, road, air, pipeline and intermodal
Maritime transport

Maritime zones, INCO terms, storage and handling decisions
Maritime zones
·Exclusive economic zone contains 95% of fish stock, this helps to create jobs and is vital for feeding the people
INCO terms
·Why establish International Commercial Terms
oConsistency in interpretation
oParties can assess their liability before striking a deal
oConvenience of having ‘shortcut’ agreements
oUnderstanding the value contained in a quoted price (what it includes)
·Each incoterm is a short-hand description of which costs will be paid by which party – buyer or seller
oTransportation- specifically which legs of the transport loading, sea, unloading, truck/train, delivery to final destination
oExport/import taxes
oAdministration/clearance through export/import control
oInsurance
·
·Some important things to clarify when contracting internationally
oWhich set of Incoterms apply – the definitions differ between the 2000 and 2010 version
oWhich law applies and which court will have jurisdiction – possibility of arbitration/mediation to resolve disputes
oWhich particular incoterm are selected
oDoes the contract alter the meaning/interpretation of the selected incoterm – arguably the most dangerous section of any commercial contract is the interpretation section
oEssential ‘boilerplate’ clauses: No Variation, Entire Agreement, No Representation
Storage/handling decisions in inventory strategy
·
·Storage decisions
oSite selection
§Finds specific real estate as a storage location
§Weighted checklist is a good approach
oSizing the facility
§From inventory policy, determine the amount of inventory to be stored, space needed
§Determine the facility’s seasonal use
§Balance the use of privately-owned space with rented space (mixed strategy)
oMixed strategy for warehouse space
§
oFacility configuration
§Configuration affects handling costs in a high throughput facility, but less important otherwise
§Square or rectangular shapes are best (L-shaped designs are poor unless conveyors used)
§Single story designs are popular for high throughput facilities and land costs are prohibitively high
oSpace layout
§Configuration of racks and aisles in the building
§Space and layout affects building dimensions and size
oDock design
§Determined by the number of rail cars along the side of a building or the number of truck stalls needed
When is a pool point likely to be an advantage
·When shipment sizes are small
·When demand is far from source points
·When transport rate economies are significant
·When pool point operating costs are low relative to transport costs
·When transfer times are insignificant to service
Handling decisions
·Controlling costs
oHandling is typically a labour intensive activity
oCosts are decreased by (principles):
§Reducing distance travelled
§Increasing the number of units handled at one time
§Seeking multiple order picking in a single order-picking round trip
§Increasing storage density
oCost reduction is also achieved by:
§Carefully planning the physical layout of the building
§Carefully locating the items within the order-picking area
§Using automation and mechanical assists as labour substitutes
§Using computer systems to help plan the flow of work through the building
·System selection

·Adds place value
·Ocean transport : 83% of travel time and 60-68% of travel costs
·Inland transport: 11% of travel time and 19-27% of travel costs
Distribution of transport costs along the value chain
·
Inland transport
·Road
·Rail
oType of fruit
oDistance travelled
oCosts
oUrgency
·Problems in SA
oService delivery is not meeting the necessary levels of efficiency
oRoad freight operators do not load their trucks according to the recognised standards
oInefficient use of rail is having negative effects on the containerised transport of goods
oShortage in the provision of transport for the fruit industry
oLack of modal collaboration
Handling of fruit
·Materials handling is very important when it comes to fruit
·It can be handled in one of two ways
oPallets
oOn pallets, inside containers
Containerisation
·Refrigerated containers are mainly 20’ or 40’ containers
oPorthole container
oIntegral container
·Porthole containers are insulated containers with two holes or ports in the end wall
oThey do not have an integral refrigeration unit
oThey have larger internal volume and payload than the integral containers
oCold air is supplied by the ship’s central cooling plant
oCool air is blown in at the bottom and the war air is removed at the top
oClip-on units are used to keep the porthole containers cool when not onboard a ship
oIt is also important that there is sufficient airflow inside the containers
·Integral containers
oBuilt-in cooling mechanism
oPowered by electricity and are therefore self-sustainable
oRefrigeration unit is arranged in such a way that the external dimensions of the container meet International Safety Organisation (ISO) standards and thus designed to fit into the container ship cell guides
oWhilst being transported onboard a ship, integral units have to be connected to the on-board power supply system
oThe number of refrigerated containers that may be connected at one time depends totally on the capacity of the ship’s individual power supply system
oContainers that are stacked in the harbour are connected to the terminal’s power supply
oContainers that are transported from their inland destinations by road or rail are kept cold with the help of diesel generators
oAir flows through the integral container from the bottom to the top
oOrdinarily, the ‘warm’ air is sucked out from inside of the container
oIt is then cooled in the refrigeration unit and subsequently blown back into the container as cold air
oIn order to ensure adequate circulation of the cold air throughout the container, the floor is provided with gratings
oPallets form a supplementary space between the container floor and the cargo which also results in a satisfactory airflow channel
oIn addition, the side walls of the container are ‘corrugated’, which ensures adequate air flow there too
oIn the upper area of the container, sufficient space (at least 12cm) must similarly be provided for airflow
oTo ensure vertical flow from bottom to top, packaging must also be appropriately designed and the cargo must be sensibly stowed
oIn addition to temperature regulation, integral units must also allow a controlled fresh air exchange, for example by removal of metabolic products (CO2) and ethylene in the case of transporting fruits
The fruit export supply chain for reefer containers
·Step 1: provision for crop estimates
·Step 2: re-supply of empty reefer containers
oEurope, ME or Far East
oMinimum time required for ordering and delivering empty containers is about 4 weeks
·Empty containers are transported to the container depots, where the reefer containers are prepared for export
·A container is prepared for export as follows:
oContainer structure is inspectedà container is then washed and left to drip dry
oContainer is moved to pre-trip towers where the refrigeration unit is under power for 4-6 hours, with special shipments up to 24 hours
oContainer is then presented to the PPECB for export approval
oContainer is ready for trip
oPre-trip process lasts 2-4 days on average
oContainers are transported to packing stations
oOnce in the port the containers are stacked according to certain criteria, such as port of discharge, vessels
oPrior to stack closing, a central stowage co-ordinator of the shipping line allocates stowage areas on the vessel, based on the info provided by the exporter or agent, at the time of booking
oFactors taken into account to facilitate the stowage of the containers are the port of discharge and the gross weight of the containers
oShipping leg of export process is relatively uncomplicated, with the exception of the port delays and the knock-on effect to the schedules
oThe ship receives a manifest, which is the document with the carrying instructions for the containers, as well as the PPECB letter
oThe vessel is required to report any inconsistencies to the necessary officials and monitor the containers as well as repair malfunctions
oWhen special commodities are being shipped, then the vessel is required to report daily temperatures to both the PPECB and the shipping lines
oPrior to the arrival of the ship in port of discharge, the vessel receives a pre-arrival telex which allows the ships staff to plan the unplugging of the reefers and thus limiting the off power period
oThis port may not be the port of final destination and may be a transhipment port, where the terminal operator again takes responsibility for the container until it is loaded onto the on-carrying vessel
oUpon discharge, the port operator ensures that the containers are plugged in immediately and monitored every day
oPrior to the arrival of the vessel in the final port of discharge, the shipping line notifies the receiver, and also supplies the local customs with the shipping manifest
oThe container is then cleared by the receiver or receivers’ agent and then collected for further transportation by road, rail for further delivery to the consignee
Inventory
Inventory functionality and definitions
·Manufacturer – inventory risk is long term
oInventory commitment begins with raw materials and ends with finished goods
oSometimes they have to store the goods as well
oInventory commitment is deep and of long duration
·Wholesaler
oPurchases large quantities from manufacturers and sells smaller quantities to retailers
oSeasonal products mean stockpiles developed
§Increases depth and duration of risk
·Retailer
oInventory management is about the velocity of buying and selling
oPurchase a wide variety of products and assume substantial risk in marketing process
oRisk is broad but not deep
oHigh cost of store location, retailers place prime emphasis on inventory turnover
·Inventory functionality
oInventory perspective, ideal situation is a response-based SC
§Not achievable in practice
oInventory is a current asset that should provide return on capital investment
oFour functions: they require inventory investment to achieve operating objectives
1.Geographical specialisation – geographical positioning across many manufacturing and distributive units of an enterprise
·Invent maintained different locations/stages of value creation process allows specialisation
2.Decoupling – allows economy of scale within a single facility and permits each process to operate at max efficiency rather than entire process constrained by slowest
3.Supply and demand balancing – accommodates elapsed time between invent availability and consumption
4.Buffering uncertainty – accommodates uncertainty related to demand in excess of forecast or unexpected delays in order receipt and order processing in delivery and is typically referred to as safety stock
·Inventory definitions
oInventory policy
§Consist of guidelines regarding what to purchase/manufacture, when to take action and in what quantity
§Includes decisions regarding geographical inventory positioning
·Advantageous to use geographic postponement strategy, centralising invent position for items with high demand uncertainty or high value
·Speculative positioning better for low value of quick customer accessibility
§Inventory management practices
·Independently manage inventory at each stocking facility
·Central inventory management of all stocking locations
oEffective communication and co-ordination
oIncreased availability of info tech allows this to be implemented
oCan reduce demand uncertainty
oService level
§Performance target specified by management, states invent performance objectives
§Measured in performance cycle times, case fill rate, line fill rate, order fill rate
·Performance cycle – elapsed time between release of purchase order by buyer to receipt of shipment
·Case fill rate – percent of cases/units ordered that are shipped as requested
·Line-fill rate – percent of order lines filled completely
·Order fill – percent of customer orders filled completely
§Inventory management is major element of SC logs strategy, integrated to achieve overall service objectives
§High service level to increase inventory or faster more reliable transport
oAverage inventory
§Inventories rolling mean across time is average inventory
§Cycle inventory or base stock – portion of invent that results from replenishments
§Stock level – max following a stock receipt from supplier
§Replenishment order – initiated so that a stock out doesn’t occur
·Ordered before or when invent level is forecasted demand during performance cycle time
§Order quantity – amount ordered for replenishment
§Transit inventory – inventory in transit between facilities or not yet received
§Obsolete inventory – out of date stock (donated, destroyed or sold at loss)
§Speculative invent – bought prior to need to hedge currency exchange
§Safety stock – protect against demand and performance cycle uncertainty
·Only used near end of replenishment cycles
§Reorder point – defines when a replenishment order is initiated
§Inventory turns= total sales/units of average inventory
oIndependent vs dependent demand
§Consumer level= independent, don’t tell retailer when they coming to buy
·Expect item to be on the shelf
·Just in case inventory (in case consumer walks in to buy item)
§Supplier end= dependent, assembled into final products, have a schedule with their suppliers
Inventory carrying cost
·Expenses associated with maintaining inventory
·Inventory expense= annual invent carrying cost % x ave invent value
·Capital – appropriate charge on capital investment in invent varies widely
oCost of capital may vary significantly by firm/industry
oFirms that are aggressive in uses of cash (higher cost of capital %)
oIndustries with high value/short life cycle product, higher cost of capital to drive lower inventories
·Taxes – inventory held in warehouses
oUsually a direct levy, but rate ad means of assessment vary by location
·Insurance – calculated by estimated risk or loss over time
oDepends on product value and storage facility (camera’s, electric fence ect)
·Obsolescence – cost from deterioration of a product during storage (sell by date)
·Storage – facility expense related to holding rather than handling the product
oAllocated on requirements of specific products since it’s not always related to value
Planning inventory
·Consists of when and how much to order
·When to order
oReorder point can be specified in terms of units or days
oR=D x T (R= reorder point, D= average daily demand, T=average performance cycle length)
oR=D x T + SS (SS=safety stock)
·How much to order
oLot sizing balances inventory carrying cost with the ordering cost
oAverage inventory is half the order quantity
§Larger order quantityàlarger average inventàgreater annual carrying costs
§Larger order quantityàless ordersà lower ordering costs
oEconomic order quantity (EOQ)
§Minimises the combined invent carrying and ordering cost
§EOQ=
·Co=cost per order, Ci=annual invent carrying cost
·D=annual sales volume, U= cost per unit
§Major assumptions
1.All demand is satisfied
2.Rate of demand is continuous, constant and known
3.Replenishment performance cycle time is constant and known
4.There is a constant price of product that is independent of order quantity or time
5.There is an infinite planning horizon
6.There is no interaction between multiple items of inventory
7.No inventory is in transit
8.No limit is paced on capital availability
§Other adjustments
1.Production lot sizes
oMost economical quantities from manufacturing perspectives
2.Multiple-item purchase
o1+ items bought concurrentlyàquantity and transport discounts
3.Limited capital
oBudget limitations for capital investment
4.Dedicated trucking
oFixed cost considerations
5.Unitisation
oQuantity discounts
Managing uncertainty
·Two types of uncertainty: demand and performance cycle
·Demand uncertainty
oSales forecasting estimates unit demand during invent replenishment cycle
oGood forecasting system still exceeds or falls short of actual numbers
oProtect against a stockout, safety stock is added to base inventory
oAverage inventory= half order quantity + safety stock
oNormal distribution is used (bell shaped: mean=median=mode)
oPredicting demand during performance cycle using normal distribution=std dev
§68.27% 1 std dev, 95.45 2 std dev and 99.73 3 std dev
·Performance cycle uncertainty
oOperations cannot assume consistent delivery
oPlanner should expect actual performance cycle experience will cluster near the expected value and be skewed toward delayed deliveries
oPoisson frequency distributions
§Smaller the meanàgreater the degree of skewness
·Safety stock with combined uncertainty
oThis requires combining two variables
oDuration of the cycle in the SR is independent of daily demand
·Dependent demand replenishment
oInventory requirements are a function of known events that are generally not random
oDoes not require forecasting as there is no uncertainty
oNo specific safety stock needed
oRests on two assumptions
§Procurement replenishment to support planning is predictable and constant
§Vendors and suppliers maintain adequate inventories to satisfy 100% of purchase requirements
oApproaches to implement safety stock into dependent demand
§Safety time – item ordered earlier than required to assure timely arrival
§Over-planning top-level demand – increase requisition by a quantity specified by some estimate of expected plan error
§Utilise setting safety stocks directly to component rather than to item of top-level demand
Inventory Management Policies
·Inventory management implements inventory policy
1.Pull approach uses customer demand to pull product through distribution channel
2.Push or planning approach proactively allocates or deploys inventory on the basis of forecasted demand and product availability
3.Hybrid uses a combination of push and pull
·Inventory control
oManagerial procedure for implementing an inventory policy is inventory control
oAccountability of control measures units on hand at specific location and tracks the +/-
§Manual or computerised basis
oPerformed on perpetual and periodic basis
oPerpetual review
§Continuously reviews invent levels to determine replenishment needs
§Accurate tracking of all SKU’s is required
§ROP=D x T + SS
·ROP=reorder point, D=average daily demand
·T=average performance cycle length, SS= safety stock
§Order quantity is determined used EOQ
§Compares on-hand and on-order inventory to item’s reorder point
·On-hand + on-order quantity<established reorder pointàreplenishment
oI +OQO≤ROP, then order OQ
oInvent on-hand + invent on order from suppliers ≤ ROP, then order the order quantity
oPeriodic review
§Reviews the invent status of an item at regular intervals (weekly or monthly)
§ROP= D(T + P/2) + SS
·D=average daily demand, T=average performance cycle length
·P=review period in days
§Average inventory formula is:
·Iaverage= OQ/2 + (P x D)/2 +SS
·Reactive methods (pull inventory system)
oResponds to channel members inventory needs by drawing the product through the distribution channel
oReplenishment shipments are initiated when available warehouse stock levels fall below a predetermined minimum or order point
oAmount ordered is based on lot-sizing formulation
oClassical reactive inventory logic is rooted on assumptions
§All customer market areas, and products contribute equally to profit
§Infinite capacity at source (product produced as desired and stored)
§Infinite inventory availability at supply location
§Performance cycle time can be predicted and cycle lengths are independent
·Each performance cycle is random
§Operates best when customer demand patters are relatively stable and consistent
§Determine each distribution warehouse’s timing and quantity of replenishment orders independently of all other sites, including the supply source
·Planning methods
oUse a shared database to co-ordinate inventory requirements across multiple locations or stages in the SC
oCan occur centrally to co-ordinate inventory allocation and delivery to multiple locations
oCan co-ordinate inventory requirements across multiple channel partners (manufacturers)
oAdvanced planning and scheduling (APS) systems illustrate the capability of planning applications
oAPS systems computerise the process, important that logs managers understand the underlying logic and assumptions
oTwo inventory planning methods: fair share allocation and distribution requirements planning (DRP)
oFair share allocation
§Provides each distribution facility with an equitable distribution of available invent
§Inventory planner determines amount of invent that can be allocated to each warehouse from available invent at the plant
oRequirements planning (RP)
§Approach that integrates across the SC, taking unique requirements into consideration
§Materials RP vs DRP
·MRP is driven by a production schedule (dependent demand)
oCoordinates scheduling/integration of materials into finished goods (controls invent until assembly/manufacturing is complete)
·DRP is driven by SC demand (independent demand)
oCoordination once finished goods are received in plant warehouse
oCoordinates invent levels, schedules and reschedules invent movement between levels
·Close coordination between the two systems = min safety stock
§Time buckets – projects one period of activity
§Constraints
·Require accurate and coordinated forecasts for each warehouse
oNecessary to direct flow of goods through SC
oSystem does not maintain excess invent at any location
·Requires consistent and reliable product movement between warehouse facilities
oUncertainty reduces the planning systems effectiveness
·Subject to system nervousness or frequent rescheduling due to production breakdowns or delivery delays
Collaborative Inventory Replenishment
·Quick response (QR)
oTechnology-driven cooperative effort between retailers and suppliers to improve invent velocity while closely matching replenishment supply to consumer buying patters
oImplemented by sharing retail sales for specific products between SC participants to facilitate right product assortment availability when and where is required
oContinuous info exchange regarding availability/delivery reduces uncertainty and increases flexibility
oFast, dependable order response, invent committed as requiredàincreased turnover/availability
·Vendor-Managed Inventory (VMI)
oModification of QR that eliminates need for replenishment orders
oGoal create SC arrangement so flexible/efficient that invent is continuously replenished
oQR customer makes decision, VMI supplier assumes more responsibility
·Profile replenishment (PR)
oSome businesses are experimenting with this sophisticated collaboration
oPR extends QR and VMI by giving suppliers right to anticipate future requirements
oSupplier can simplify retailer involvement by eliminating need to track unit sales and invent level for fast-moving products
Inventory management practices
·An integrated invent management strategy defines the policies and process used to determine where to place inventory and when to initiate replenishment shipments
·Strategy development process employs three steps to classify products and markets, define segment strategies and operationalise policies and parameters
·Product/market classification (fine-line or ABC classifications)
oObjective is to focus and refine invent management efforts
oGroups products, markets, customers with similar characteristics to facilitate invent management
oPareto 80/20 analysis
·Segment strategy
oDefine invent strategy for each product/market group
oService objectives, forecasting method, management technique, review cycle
oKey realisation is that product segments have different degrees of importance with respect to achieving the enterprise mission
·Policies and parameters
oDefine detailed procedures and parameters
oProcedures define data requirements, software applications, performance objectives and decision guidelines
oParameters delineate values such as review period length, invent carrying cost %, order quantities and reorder points
Green Logistics
Key considerations
·What drives your decision making when trying to build a world class SC
oCost, service, differentiation
·Do you strive to be the best in the world
·What price are you willing to pay to achieve this
·What is the potential cost of getting it wrong
·Are your efforts aligned with your customers and your partners
Sustainability
·Broadens the concept of performance
·
oOften we can only get two of the above
§Social and economic
§Environmental and economic
There is still widespread uncertainty about how to move forward with green SC initiatives
·Knowing – become educated
·Doing – measure company’s carbon footprint and ID change levers
·Being – embark on business case-supported initiatives
·
Freight transportation negligible considerations in company strategy with regards to environmental responsibility
·Current business practices such as international sourcing and quick turnaround times challenge this by extending transportation distances and minimising lead times in the SC
Shippers and carriers have a key role to play here with green SC initiatives
·Retain drivers
·Improve equipment
·Shift modes
·Improve transport efficiency
·Change packaging
·Optimise network, loads, docks and routes
·Automated billings
·Move toward greener buildings
Future of intermodal transport solutions
·Intermodal is the seamless use of more than one transport mode
·It is not the same as multi-modal, container transport and is not limited to international shipments
·Seamless is important, implies ‘unitisation’ of some form
What is extra distance
·The difference between the number of kms vehicles actually run vs how many they could have run with proper planning and execution (data, info required)
·Economic impact – more fuel is required to complete delivery
·Environmental impact – more CO2 produced
·Used to conduct root cause analysis
The way forward
1.Admit that there is a problem
2.Volatile energy costs substantially drain company resources
3.New proposed carbon taxes will force companies to cut energy use of pay penalties
4.Pressure from customers, shareholders and advocacy groups continues to mount for companies to reduce their carbo emissions
Business need to unite
Reverse Logistics
Reverse Logistics Systems
·Four important flows along a SC
oMaterials, info, financials and demand
·Critical area of SCM
·Logs systems designed to handle product flows in one direction
·Manufacturers did not expect their products to fail or receive them back from customers
·Reverse flows are goods/materials moving upstream in the SC
·Process of returning these items to source and replacing or repairing them is often more expensive than the delivery of the original item to the market place
·High valued items or high volumes of product returns
Definition
·Reverse logistics is the management of all the activities involved in the flow of goods, demand information and money in the opposite direction to the primary logistics flow; a reduction in the generation of waste, and the management of the collection, transport, disposal, and recycling of hazardous as well as non-hazardous waste in a way that maximises the long-term profitability of the business
Critical area of a SC
·Chain of production
oInventory
oTransportation
oWarehousing
oPackaging
·Critical nature of reverse logs (PESTLE framework) – holistic overview of growing importance
oPolitical
oEconomic
oSocial
oTechnological
oLegal
oEnvironmental
Reverse logs activities and channels of distribution
·Different channels
oValue carriers
oReturns of unsold goods
oProduct recalls
oProduct returns and exchanges
Value carriers
·Reusable goods: intrinsic value
oSome may be worth more than the value of the products that they carry at a single time
·Flow in opposite direction to primary flow
·Part of the inventory of the business
·Fluctuations in demand – result in surplus or shortage if not managed carefully
·Level of shrinkage needs to be known
·Reduction in inventory – breakages, age, theft
·Cost to a business
·Continually reused
·Properly designed
·Examples- empty milk drinks and bottles, empty crates of beer, empty gas cylinders
·Costing of value carriers
oInitial purchase, subsequent management and continual replacement
oTwo main categories of value carriers
§Distributed to consumer à used repeatedly
·Deposit
·Carrier specific to the duty it performs
·Cost normally capitalised and depreciation is charged as a fixed cost
·Where the cost of the value carrier is small in relation to the cost of the goods movedà included in the selling price
·Plastic crate made for soft drinks
§Used in a closed loop
·Pallets, containers, roll-tainers
·Not sold; used in parts of the logistics chain to facilitate movement/storage
·Names of owners
·Moved with the primary flow and the returned
·Costs – overhead expense
·Rail operator
·Available for hire for third parties (containers, pallets)
·Higher costs than the purchase of items à collected/dropped at the depot closest to the goods
oCosts of returning the carrier and the management time and effort are reduced
·Depots
oContainers and rail wagons
·Road transport
oBackhauls
Return of unsold goods
·Certain industries
oNewspapers, magazines and textbooks
oIncentive for downstream members to carry more inventories
oRisk
oAnalyse customer accounts not only for profitability, but also for hidden costs
·Bread industry
oRepackaged and relabelled – now sold as croutons
oBarcoding
oPackaging must be disposed of as waste
·Examples – magazines, books, newspapers
Product returns and exchanges
·May be caused by:
oDamaged goods, incorrectly ordered/supplied goods
oWarranty claims, product support, after-sales service
·Examples – damaged clothing, incorrectly ordered items, warranties and repairs of items
·Patterns of returns must be ID and corrected
·Damaged goods
oMovement or storage
oSooner damage detected= cheaper to rectify
oValue
·Incorrectly ordered goods
oCustomers and suppliers to share an electronic info system
§Achieved by electronic data interchange
·Incorrectly supplied goods
oWho will pay for the mistake
oAll parties are negatively affected
·Warranties and repairs
oNon-conformance problems
oDetect defective goods ASAP
oReturn goods: recycled, reworked, destroyed or otherwise disposed of
·Product recalls
oDefective goods are recalled for rework or replacement
oAutomotive industry (VW)
oDifference between recalls and returns
§Logs functions: small quantity of goods
§Design or manufacturing defect: every item
§Who is financially responsible
oReverse logs can be substantially more expensive than forward flow
§Cause
§Quality
·Waste management
oAlways be generated
oSort waste as close as possible to the source
oTransport it as cost effectively as possible
oDisposing and recycling
·Hazardous and non-hazardous waste
oHazardous – negative effect on environment and human health
§Extreme to high hazardous waste (H)
§Moderate to low hazardous waste (h)
§Radioactive waste, toxic waste and tyres
oNon-hazardous – no effect on environment and human health if managed properly
§Domestic waste, garden refuse and light industrial and commercial products
oReduction of waste in general
§Greatest challenge
§Environmentally aware
oCollection of waste
§Sorting waste as close as possible to the source
§Hazardous waste
§General waste
oTransport of waste
§Dependent on the most economical solution
§Road transport
§Barge
§Rail
§Hazardous waste
oDisposal of waste
§Dumping ground
§Waste disposal site
§Classification of waste sites
·H class site
oEncapsulated
oMedical and pharmaceutical
·h class site
oRecycling of waste
§Glass, plastic, tin, aluminium and paper
§Reasons for recycling
·Reduction of the volume of waste
·Results in less overall energy utilised and less pollutants emitted
·Conservation of raw materials
§Most frequently used categories of recycling
·Separation at source – most effective method (occurs at home or industry)
·Scavenging – not encouraged but does still take place at some dumps (health reasons)
·Street pick-up – paper and boxes left on the pavement and collected by contractors
·Creating compost from garden refuse – reduces volumes of waste at site
oMaterial recovery facility
§Drop-off point, conveyer system and storage containers
§Balers and a rejection point
§Workers are stationed at the conveyer belt
Differences between forward and reverse logistics
·Forward logistics
oSales and marketing forecast plan
oSingle or limited origin of products
oDistribution planning possible
oHigh visibility
oCost known or can be estimated before shipping
·Reverse logistics
oDifficult/impossible to forecast
oMany-to-one distribution network
oReactive planning for distribution
oLow visibility into product flows
oDifficult to predetermine costs
Financial implications of reverse logistics
·Estimates are that returns range from 3-50% depending on the product
·Retailers lose 3-5% of gross sales to returns accounting for 4.5% of the cost of logistics
·Internet returns are about double the counter saes returns
·Cost of reverse logs is significant and increasing
·Cost adds no value to the logs function of providing the goods at right time/place
·Costs for value carriers must be carefully monitored
·Costs of items not integral to the product delivered need to be minimised
·Costs associated with waste
Life-cycle assessment (LCA)
·Quantitative determination of the resource and energy use and environmental burdens of a product or process over its entire life cycle
·Cradle to grave perspective
·Comparative nature
·Can also be used to compare distribution strategies
·Sustainability efforts can be included during a product’s life cycle:
oDesign – incorporate materials into the product that can be recycled and try to use materials that have low energy requirements during the manufacturing process
oSource – source parts and materials from suppliers that comply with environmental regulations (source locally to reducing transport requirements)
oManufacture – implement an effective environmental management system and try to reduce energy consumption at manufacturing plant (make sure waste products from manufacturing process are collected, reused or recycled)
oDistribution – reduce the use of packaging during distribution, consolidate loads where possible and measure the carbon footprint of your logs decision
oPost-sale service – try to repair products instead of always replacing them (provide feedback to design/manufacturing on defects to try limit risk of defects)
oReturns/recycling – sell returned products into secondary markets where possible (implement remanufacturing and recycling programmes)
