Research To The Optimization Model, Method And Application To Express Logistics

The logistics industry is the basis and lifeblood of national economy development and its development level has become an important indicator to measure the modernization and comprehensive strength of countries. Taking the advanced information technology as a measure, developing the modern logistics industry in China, and it is the bounden duty and obligation of the majority logistics researchers. The research to logistics model, method and application has very important practical significance. The main work of this paper can be summarized as five points.(1) The modeling method of express logistics optimization problem. On the basis of the basic terminology definition of express logistics optimization problem, the express logistics double optimization modeling method and steps are proposed, and the TOPSIS method is applied to comprehensively evaluate the multi-objective optimization problem.(2) The solving framework of express logistics optimization problem. Based on the complexity analysis of express logistics optimization problem, the solving framework of express logistics optimization problem is constructed.(3) The solving approach to macro configuration optimization problem of express logistics. On the basis of comprehensive evaluation and sorting of alternative distribution centers, considering the weight uncertainty of multi-criteria decision-making criteria, a simple and intuitive comprehensive evaluation method is proposed. At the same time, some factors are analyzed to the distribution center location, and the specific steps and methods of location decision-making are proposed.(4) The solving approach to micro path optimization problem of express logistics. The standard ant colony optimization is significantly improved, and the improved algorithm is applied to solve the micro path optimization problem of express logistics.(5) The application of express logistics optimization. On the basis of postal express business, the express logistics optimization application examples are given, and the impact analysis of various factors are presented.With the supportting of proposed model and method, the express logistics company will be able to conduct business within the optimized logistics system, and quickly realize the goals of maximizing the resource utilization and reducing operating costs.
