The scalable warehouse example

Summarizes the problem.

The scalableWarehouse.mod file is a scalable version of the warehouse location model that is described in detail in Warehouse location in the Language User’s Manual.

This section assumes that you are familiar with the integer and Boolean variables used to solve this problem as explained in that document. Here is a summary of the problem:

A company is considering a number of locations for building warehouses to supply its existing stores. Each possible warehouse has a fixed maintenance cost and a maximum capacity specifying how many stores it can support. Each store can be supplied by only one warehouse and the supply cost to the store differs according to the warehouse selected. The application consists of choosing which warehouses to build and which of them should supply the various stores in order to minimize the total cost, which is the sum of the fixed costs and the supply costs.

The model instance used in this section considers 50 warehouses and 200 stores. The fixed costs for the warehouses are all identical and equal to 10. The warehouse project folder contains the model scalableWarehouse.mod.
