基于熵和前景理论的大型制造企业供应商评价研究

Supplier Evaluation for Large Manufacturing Enterprises Based on Entropy and Prospect Theory

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决策方法对供应商进行评价,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。

Due to existing potential development prospect during the suppliers＇ cooperation period,the prospect theory is applied to determine prospect values of various indicators in this paper. 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.
