摘要

The p-median problem is location-allocation problem that takes into account the average (total) distance between demand points and facility. The practical utility of the problem is obvious by the number of solutions developed in the literature. A formulation is presented and computational experience is offered. Lexi-search algorithm can be used effectively, which takes care of simple and combinatorial structure of the p-median problem. For this problem a computer programme is developed for the algorithm and is tested. !t is observed that it takes less time for solving fairly higher dimension problems also. For this problem the definition, notation and algorithm are illustrated with the help of a numerical example.
