Detailed Description

Example: Locating warehouses

A company needs to construct warehouses to supply stores with goods. Each warehouse possibly to be constructed has a certain capacity defining how many stores it can supply. Constructing a warehouse incurs a fixed cost. Costs for transportation from warehouses to stores depend on the locations of warehouses and stores.

Determine which warehouses should be constructed and which warehouse should supply which store such that overall cost (transportation cost plus construction cost) is smallest.

Taken from: Pascal Van Hentenryck, The OPL Optmization Programming Language, The MIT Press, 1999.
