物流中心选址求解模型与方法研究

Study on Model Building for and Solutions of Location Selection for Logistics Center

物流中心的选址是物流中心规划设计时要解决的重要决策问题。在根据运输总距离或运输总成本最小,构建二次规划模型的基础上,围绕物流中心选址时通常有多个备选区域这一实际情况,考虑土地价格、政府扶持力度、自然条件、交通便利程度、建设周期5个影响因素,运用混合多属性决策方法确定物流中心备选区域,并加入约束条件,对已建模型进行优化,从而确定物流中心最优位置,最后通过算例分析,验证所提出的优化模型的可操作性和优越性。

The location of logistics center is an important decision in its planning and design. This paper builds two quadratic programming models on the premise that the transportation distances is the shortest or the transportation costs are the lowest. Given the general practice of multiple alternatives for location selection, the paper takes into account five factors - the land prices, government support, natural conditions, the transport facilities, the construction period - to determine the optimal area using the hybrid multi-attribute decision-making method. What is more, the auxiliary optimization mathematical model is extended by adding some constraint conditions. Finally, the feasibility and practicality of the proposed model is verified by an example analysis.
