An Application of Interactive Fuzzy Satisficing Approach with Particle Swarm Optimization for Multiobjective Emergency Facility Location Problem with A-distance

Abstract

This paper extends optimal location problems for emergency facilities to multiobjective programming problems by considering the following two objectives: one is to minimize the maximal distance of paths from emergency facilities to hospitals via accidents, and the other is to maximize frequency of accidents that emergency facilities can respond quickly. In order to find a satisfying solution of the formulated problems, an interactive fuzzy satisfying method with particle swarm optimization is proposed. Computational results for applying the method to examples of multiobjective emergency facility location problems are shown
