Bi-level programming model and solution algorithm for the location of e-business logistics distribution*

摘要

For the current status of e-commerce logistics and distribution terminal node layout,this article considers planners and customers both benefit, while also considering the impact of the end node distribution route for cost. A bi-level programming model of end nodes location was constructed. The upper level model is the smallest in the conditions of transport costs and fixed costs as much as possible to attract customer demand, lower programming model considers the distance, the price of services and quality of service that influence customer choice behavior, and customer demand for the costs of terminal nodes distribution is studied.Finally, a numerical example verifies the feasibility of the model and algorithm.
