城市共同配送中心选址研究--基于生态位和混合整数规划法视角

摘要

在分析影响选址生态适宜性因素的基础上，引入生态位适宜度模型进行第一次筛选，旨在揭示资源现状对城市可持续发展的适宜性程度。此外，采用混合整数规划模型对剩余备选方案进行二次筛选，并以Z市为例，计算各备选点与理想点的距离远近，确定最终共同配送中心方案。实证结果表明该模型能较好地处理城市生态环境与共同配送中心选址问题，以期为其他城市共同配送选址提供一定借鉴。建议政府着眼城市未来发展，加强共同配送中心的基础设施建设，合理布局，提高资源利用率，促进整个共同配送中心协调运作。%Based on the analysis of ecological suitability factors that influence site selection,introduce the niche fitness model to fil-ter for the first time,aiming to reveal the degree of suitability between the status of resources and urban sustainable devel-opment.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 dis-tribution 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 cen-ters,rational distribution,improve resource utilization,and promote co -operation with distribution centers across the Community.
