Study Of Distribution Centers Location Based On Port

Port logistics distribution center is comprehensive international logistics center in port radiation region which mainly operates import and export cargoes distribution. It is also international multimodal transport node and port transportation platform. In the promotion of our country port logistics, the construction of the port logistics distribution center will become the priority among priorities in future development. Before the construction of new port logistics distribution center, carrying on the reasonable location planning means important practical significance to enhance the competitiveness of the port logistics service.In this paper, through the analysis of the characteristics of port logistics distribution center, study the port new logistics distribution center location problem. Firstly, analyzes the definition and connotation of port logistics distribution center, puts forward the function orientation of port logistics distribution center and expounds the port logistics distribution center on-downstream business process. Secondly, analyzes many factors of port logistics distribution center, draws the distinctions of location problem between port and other logistics distribution center and puts forward the principle, influence factors of port logistics distribution center location. Then, combines the characteristics of port prominent location problem of distribution center, considers the influence factors of all the distribution process, determines the target of location problem, sets up the location bi-level programming model based on the target, the upper layer to achieve the main goal of decision of port logistics distribution center optimal cost and lower auxiliary decision target customers realize optimal. Finally, according to the target location selection and the characteristics of bi-level programming model, uses the genetic algorithm to solve the model, designs genetic algorithm procedure for the specific model, then designs rational the examples and solved by software, verifies the effectiveness of the model and algorithm.
