This paper proposes a new multiobjective location problem for emergency facilities, e.g. ambulance service
stations and fire stations. In the problem, one of the objectives is to minimize the maximal distance of the paths from the
located emergency facilities to hospitals via accidents. The other is to maximize the frequency of accidents that the emergency
facilities can respond quickly. An interactive fuzzy satisficing method with particle swarm optimization (PSO)
method is proposed for finding a satisficing location for the problem. Computational results illustrate the method with
numerical examples of the multiobjective location problem.
