Abstract: 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.

Key words: distribution center location, time constraints, 0-1 programming cutting plane method
