摘 要:针对大型制造企业供应商在合作期内存在潜在发展前景因素,因此在供应商评价管理问题中,依据协同性、服务成本、服务中断、服务信任准则构建大型制造企业供应商评价指标体系,运用前景理论确定各个指标的前景值,以此构造评价矩阵,结合熵权法确定评价指标的权重系数。引入TOPSIS决策方法进行供应商评价,根据马氏距离和灰色关联改进距离度量方法,实例分析说明了该评价方法的有效性和可行性。通过三种不同评价方法的比较分析发现,供应商的前景因素对于供应商评价结果具有较大的影响。

Abstract: A supplier evaluation index system is constituted for large manufacturing enterprises. The system is based on such criterion as cooperation, service cost, service interruption and service trust. Due to existing potential development prospect during the suppliers' cooperation period, the prospect theory is applied to determine prospect values of various indicators. The evaluation matrix is built accordingly and then, weights for each individual indicator are settled with entropy. The TOPSIS method and Mahalanobis distance plus grey correlation are introduced into the evaluation system. Finally, an example is given to show the effectiveness and feasibility of the proposed indicator system. By comparing three evaluation methods, it is found that suppliers' development prospect has great impact on evaluation results.

Key Words: prospect theory; large manufacturing enterprise; supplier

引言

在产品生产过程中大型制造企业对于供应商提供的零部件和部件依赖度较高,将近50%- 70%的产品成本来自于零部件采购[1]。供应商的评价结果将会影响制造企业的库存管理、生产计划与控制,对于客户的产品成本、交货期也会有显著的影响[2]。因此,在供应链管理中供应商的合理评价变的极为重要[3]。目前,供应商与制造企业的关系研究主要包括创新性管理、绩效管理、供应链管理三个方面,Azadegan[4]利用组织认知理论研究供应商创新性与制造企业产出之间的联系,通过实证分析表明供应商创新性对于制造企业产出具有积极影响。李随成[5]从供应商网络视角研究供应商创新对于制造企业产品创新的影响,研究结果发现供应商创新性对制造企业产品创新具有积极作用。……
