Abstract: The direct relationship of supply and demand between manufacturer and retailer was brought into the research on the site selection and layout of logistics distribution center, and constructed the nonlinear mixed 0～1 programming model of the site selection and layout of logistics distribution center was conducted through improving the linear programming model of existing general transportation problem with introducing the 0～1 variable of the selection of logistics distribution center. At last, the optimal solution of freightage and the optimal number were obtained, by which the logistics distribution center will be constructed by solving this model with LINGO. Thus, to solutionssuch issues as the site selection and layout of logistics distribution center were put forward.

Key words: traffic and transportation engineering, logistics distribution center, site selection and layout, the direct relation between supply and demand, optimization model

摘要： 将生产商与销售商之间的直接供需关系纳入到多物流配送中心选址布局问题的研究当中，通过引入物流配送中心选建0～1变量，对现有一般运输问题的线性规划模型进行改进，从而建立多物流配送中心选址布局问题的非线性混合0～1规划模型，并通过lingo语言编程对该模型进行了求解，既实现了货物运输方案最优，也实现了物流配送中心选建数量最优，为多物流配送中心选址布局问题的解决提供一定的理论借鉴。
