This paper provides insights to locate a finite number of distribution  centers to provide a quick response time for disaster relief  incorporating social costs within the modeling framework. We explore  theoretical aspects of the problem formulation and propose a model that  maximizes coverage of affected regions while minimizing human suffering  through the use of a social cost function. Our results show that the  social cost function is minimized within the area enclosed by the  Voronoi region for a chosen facility. We also propose a heuristic  algorithm to solve the problem of locating these facilities in a  reasonable amount of time. Since the quality of the solution and the  running time depends largely on the initial starting points for the  heuristic, we provide recommendations to choose the initial starting  points. The proposed approach has the potential to significantly improve  the efficiency of distributing critical supplies in disasters by  optimizing the response time.
