面向多源采购的多级供应链优化配置方法

摘要

研究多源采购策略下的多级供应链优化配置问题。针对供应链各级备选供应商数量不确定、且可能大于2个这种问题研究较少的多源采购问题，引入供应商采购比例调控因子（ SPCF）并提出基于ANP和TOPSIS的SPCF计算方法，同时以服务时间和实际采购比例为两个主要的决策变量，建立多阶段供应链优化配置模型。提出基于混合编码的改进遗传算法，并对模型求解。最终通过实例验证模型和算法的有效性，并对SPCF进行敏感性分析，得到重要的管理学启示。%Based on a multiple sourcing strategy , a research is conducted on the multi-echelon supply chain configuration ( SCC ) problem .Supply chain with uncertain number of multiple supplier options (such as more than two options) is studied.Sourcing proportion control factor (SPCF) is proposed as a multiple sourcing control mechanism .An approach based on ANP and TOPSIS is put forward to calculate the SPCF.Service time and actual sourcing proportion are adopted as two major decision variables to estab -lish an SCC model for multi-echelon supply chain .An improved Genetic Algorithm using mixed coding method of integer and real variable is proposed to solve the problem .Both the model and the algorithm are verified by demonstrative cases .At last , sensitivity analyses are conducted with a series of SPCF and sev-eral managerial insights drawn .
