Resumen

This work introduces an extension of the classical discrete p-center problem (pCP), called the stratified p-center problem (SpCP). In this extensionit is assumed that the population of each demand site is divided into different categories or strata depending on the kind of service that they require. The objective of the proposed model is to locate p centers minimizing the weighted sum of the largest assignment distances associated with each stratum. This model could be applied in humanitarian relief planning where centers of humanitarian assistance cover different kind of needs and the demand of each need may be distributed in a spatially different way.
