闭环供应链中多节点配送中心选址问题研究

Multi-node Distribution Center Allocation Model Based on Closed-loop Supply Chain

考虑闭环供应链系统中物流配送的特殊性,建立适用于闭环供应链系统的物流配送中心选址模型。闭环供应链系统的物流配送中心选址涉及到多方面的因素,除了考虑选址中的影响因素外,要考虑已有配送中心的效率,还应咨询和参考各相关管理人员或员工的意见和建议。为此,建立了一个基于效率的混合整数规划模型来解决闭环供应链系统的配送中心的选址问题。在此选址模型中,根据DEA模型对已有配送中心效率的进行评价。实例分析表明,该模型能很好地处理配送中心的选址问题,为决策者提供一种有效的优化工具。

A logistics distribution center allocation model for closed-loop supply chain system is developed taking the specific characteristics of the system into consideration.Besides normally considered factors,the model incorporates the efficiency of distribution centers.The experts＇ opinions and advices were asked for during the development of the model.The allocation model of closed loop supply chain system is set up in the form of a mixed integer programming problem with constraint of efficiency that is calculated with DEA.An example demonstrates that the model can give good results,hence be an effective optimization tool for decision-makers.
