面向电子商务农产品代购供应链的配送中心多目标选址模型

Multi-objective Location Model of Distribution Centers Oriented toward Agricultural E-business Commissioned Buying Supply Chain

针对面向电子商务农产品代购配送模式的供应链配送中心选址问题,考虑经济成本最小化和消费者满意度最大化,构建多目标决策优化模型。其中,模型经济成本主要包括固定成本、运输成本和货损成本,消费者满意度主要包括到货及时性和农产品新鲜度。由于经济成本和消费者满意度往往存在效益背反现象,在模型求解过程运用主要目标法将多目标模型转化为单目标模型,并用贪婪取走的启发式算法对单目标模型进行求解。从仿真算例求解结果可知,此方法能在满足消费者需求和农产品代购供应链总成本最小化的情况下,达到最优选址的目的。

In this paper, in view of the location problem of the distribution centers oriented toward the commissioned buying supply chain of the agricuhural E-businesses, we established the muhi-objective decision optimization model that aimed both at minimizing the economic cost and maximizing customer satisfaction, of which, the former mainly consisted of fixed cost, transportation cost and cargo loss cost and the latter consisted of in-time delivery and agricultural product freshness. Since there usually existed trade-off between the economic cost and customer satisfaction, during the solution of the model, we converted the multi-objective model into a uni-objective model, used the Greedy Dropping heuristic algorithm to solve the latter, and at the end, through a numerical example, demonstrated the validity of the method.
