一个物流配送中心选址模型及其算法

一个最优的配送中心选址方案，既可以提高物流系统的效率，又能降低物流系统的成本.在时间已经成为竞争优势的一种新资源的社会，将时间约束考虑到配送中心选址模型中无疑是一个突破.建立了一个物流配送中心选址模型，在模型中只需要知道所需配送中心的个数上限即可,松弛了以往模型中需确定所需配送中心个数的条件.模型求解算法上，采用优化方法中的0-1规划割平面法，结果表明模型具有可靠性，且计算复杂度得到降低.

Model of the Logistics Distribution Center Location and Its Algorithm

An optimal distribution center location can not only improve the efficiency of the logistic system,but also reduce the cost of logistics system as well.In the current society,time has become a new resource of competitive advantage,so taking into account the time constraints on the distribution center location model is undoubtedly a breakthrough.A model of the logistics distribution center location is proposed.In the new model it is necessary  to know the upper limit of the number of the required distribution center,thus the  relaxation of the conditions to be determined in the previous model is achieved.Finally 0-1 programming cutting plane method,which is the optimization methods,is used for model solution.At last the results indicate that the model is reliable,and the methods reduce the computational complexity of the algorithm.
