Abstract: Starting from supply chain integration, taking the maximum profit as a target and following the market regulations, a factor of demand price elasticity was introduced. By using the model of a bi-level programming, issues such as choosing addresses for distribution centers, fixing price, and the optimal carrying quantity of the clients at the distribution center were studied. In the bi-level programming model, the upper layer was used to choose addresses for distribution centers, and the lower layer was used to reflect the optimal distribution center which clients tended to choose. Aiming at the model, a heuristic algorithm was designed, the feasibility of the model and algorithm was also verified by an calculation example. The application results indicated that the model considering the maximum benefits of the whole supply chain was more applicable.
