With the rapid development of the world economy and the progress of modern science and technology,the logistics industry,as one of the most important service industries in the national economy,has rapid development of the world.In the link of logistics,transportation and delivery costs accounted for 60% per cent of the total cost of logistics is an important factor in the total cost of logistics.With the advent of the information age,and the deepening of the idea of the supremacy of customers,it will be a logistics enterprise to have a significant and far-reaching practical significance about how the logistics and distribution services for customers more effectively,how to further improve the efficiency of logistics and distribution.In this paper,through the analysis of the target enterprise mode of delivery vehicles,found the contradiction between the change of customer demand that in the process of daily dispatching in the implementation of the program and the contradiction.Existing program lack in the adjustment mechanism after the change of customer demand,it can’t send a car to the line corresponding to the change of customer demand and re-optimization.In this paper,by studying the change of customer demand contained in a product category and product weight,follow the method for the optimal path in the process of logistics distribution,and establish a set to suit the change of customer demand of vehicle scheduling optimization program,in order to effectively solve the enterprises in the logistics transportation process due to the change of customer demand the temporary transfer problem.
