Facility location Description There are a set of depot locations and a set of clients.
The cost of opening each depot, the depot capacities, and
the demand of each client is given. For all possible
delivery routes the unit shipping cost is given.
We wish to supply all the clients at the least cost.
The model is re-solved several times to study the effects
of forcing some depots open. Further explanation of this example: Similar problem: 'Applications of optimization with Xpress-MP', Section 10.3 'Depot location' (e3depot.mos)
