A Fuzzy Model for the Multiobjective Emergency Facility Location Problem with A-Distance

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.
