Fuzzy Mathematical Modeling of Distribution Network, Allocation Model Positioning in Three-Level Supply Chain Design

Economic role in all areas, particularly in the steel industry has grown dramatically. In this work 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. Distribution system generally includes three levels be so that the first level suppliers of iron ore, mining, steel and ... 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 FAHP is proposed and it’s output as input in integer programming model used. In The end presented model analyzed by software of maple12
