Abstract: The article analyseis the relation of stock, transport, and Distribution center in the system of logistics. Bymeans ofoptimizationmethod, the mathematical model of logistics Distribution center allocation is put forward. It is amixed integer programmingmodel.The algorithmwhich refers to the benders,smethod is given. Limited quantity of stipulations ensures the astringency of the algorithm.The model should be practical because of variety of reality facts have been considered.
