In this article, a new look to the field of mathematical modeling of distributed systems in terms of fuzzy location model and the theory of fuzzy has been allocated and an integer linear programming is used. The distribution system generally includes three levels so that the first level suppliers of iron ore, mining, steel and so on are placed. The second level involves locating distribution centers consider so that a limited number of distribution centers can serve as stations and the third level of local warehouses or factories in steel production are using the integer programming technique, a fuzzy mathematical model for distributed systems is presented. The second level of distribution center location selection techniques based on Fuzzy Analytical Hierarchy Process (FAHP) is proposed and its output as input in integer programming model is used. It's worth mentioning presented model is analyzed by software of maple 12.
