Optimizing Flow Networks: Problems and Solutions
[9] Patient Allocation to Hospitals as a Flow Network
We build the following flow network. There is a node vi for each patient i, a node wj for each hospital j, and an edge (vi, wj) of capacity 1 if patient i is within a half-hour drive of hospital j. We then connect a super-source s to each of the patient nodes by an edge of capacity 1, and we connect each of the hospital nodes to a super-sink t by an edge of capacity n/k. We claim that there is a feasible way to send all patients to hospitals if
