【Abstract】 Distribution center is the pivot of a logistics system. To define the location of distribution center is the key of logistics system analysis. In this paper, according to the characteristics and requirements in the selection of the location, a mathematical model applied to the location selection was established on the basis of lowest transportation cost. Genetic Algorithm was then used to solve the model, and the optimal solution of the model was obtained by selecting the encode method and genetic operator correctly, thus verifying the correctness of the model. The proposed method is also applicable to the selection of the distribution center’s location in large-scale logistics systems.更多还原
