[Abstract]:Logistics industry is the foundation and lifeline of national economic development, and its development degree has become one of the important symbols to measure a country's modernization degree and comprehensive national strength. It is an unshirkable duty and obligation for the vast number of logistics researchers to develop the modern logistics industry in China by means of advanced information technology. It is of great practical significance to carry out the research on the model, method and application of express logistics. The main work of this study can be summarized as five points. (1) the modeling method of express logistics optimization problem. On the basis of defining the basic terminology of express logistics optimization problem, the modeling method and steps of express logistics bilevel optimization model are put forward, and the multi-objective optimization problem is comprehensively evaluated by TOPSIS method. (2) the framework of solving express logistics optimization problem. On the basis of analyzing the complexity of solving the optimization problem of express logistics, the general framework of solving the optimization problem of express logistics is put forward. (3) the method of solving the optimization problem of macro configuration of express logistics is proposed. On the basis of comprehensive evaluation and ranking of alternative distribution center, considering the uncertainty of criterion weight coefficient in multi-criteria decision-making, a simple and intuitionistic comprehensive evaluation method is proposed. This paper analyzes several factors that need to be considered in the location of distribution center, and puts forward the concrete steps and methods of location decision. (4) the solution method of the microcosmic route optimization problem of express logistics. Based on the improvement of ant colony algorithm, the improved ant colony algorithm is used to solve the double layer optimization model of express logistics system. (5) the application of express logistics optimization. Based on the postal express service, the application example of the optimization of express logistics is given, and the influence of various factors on the optimization result is analyzed. With the support of the model and method of this paper, express logistics company can carry out business in the optimized "big logistics" system, and can quickly achieve the goal of "increasing the utilization of resources to the maximum extent and reducing the operating cost as far as possible".
