Planning service facility locations before sudden happening of any disaster is vital for public organizations. Selection decision for cookhouse or infirmaries is very important because of agitated situation of disaster times. In this paper, through the resemblance of selection decision for service facility locations to retailing sector, a gravity based model is offered. Attractiveness of service location and distance between demand points and the service facility are key factors in location selection of service facilities. Due to the lack of data and imprecision of estimated parameters which cause uncertainty, fuzzy logic is utilized. Instead of probabilistic value, possibilistic values as a result of using fuzzy parameters are obtained in the proposed gravity model.
