Abstract:Based on the analysis of ecological suitability factors that influence site selection, introduce the niche fitness model to filter for the first time, aiming to reveal the degree of suitability between the status of resources and urban sustainable development. In addition, using the mixed integer programming model to a second screening of the remaining options , and for example the Z city, calculate the distance of each candidate points and the ideal spot to determine the final common distribution center program. The empirical results show that the model can handle urban ecological environment and common distribution center location problem better, for other cities joint distribution site to provide a reference. It recommends that the Government focus on the city's future development, strengthening infrastructure construction joint distribution centers, rational distribution, improve resource utilization, and promote co-operation with distribution centers across the Community.
