摘要: 对已有多个配送中心存在的前提下, 新增配送中心为获取最大市场占有量如何进行有效的选址决策问题进行了研究, 建立了一个选址决策模型, 把求解的问题归结为无约束的非线性规划问题, 并给出了迭代算法, 最后对如何解决考虑多种选址影响因素及多个新增配送中心的复杂情况进行了讨论。Abstract: This paper, on the basis of more than one existing distribution centers, discusses how to make an effective decision of location for a new distribution center in order to reap maximum market share, set up a location model and regard location decision as a problem of non constraint non linear programming. An iterative solution algorithms and a numerical example are given, the model is extended to multiple factors and distribution centers location problem.
