The P-center model assists in selecting p facilities from a set of candidate facilities (n) for various locations (m), based on the OD matrix (m x n).
The input table should contain the columns for distance matrix to candidate facilities, and optionally a column for distance to closest required facilities.
The P-center (Minimax) problem is solved using the PuLP package.
The node is based on the package PuLP and here are related tools and references:
The columns representing the distance matrix between demand lcoation to candidate facilities.
The Column indicating distance to the closest required facility.
The optimum number of facilities.
