P-median Solver

The P-median model, one of the most widely used location models, locates p facilities and allocates demand nodes to them in order to minimize the total weighted distance traveled.

The input table should contain the three types of columns: demand size (e.g., population), distance matrix to candidate facilities, and optionally a column for distance to closest required facilities.

The P-Median problem will be solved using the PuLP package.

The node is based on the package PuLP and here are related tools and references:
