一种综合的供应商评价方法

Supplier Evaluation Based on Synthesis Method of Principal Component Analysis, Data Envelopment Analysis and Analytic Hierarchy Process

摘要:

针对供应链管理中供应商选择问题（VSP），尝试将综合AHP（层次分析法）、PCA（主成分分析）和DEA（数据包络法）3种方法应用在供应商评价中，避免传统的单个方法或2个方法的综合使用中各种方法本身的缺陷，尤其是解决由评价准则的相关性带来的重复评价和权值给定的客观性的问题.通过实例分析说明，与带偏好约束的AHP和DEA综合方法的评价结果进行了对比，AHP，PCA和DEA三者综合评价法能够有效降低评价的复杂程度，减少数据的冗余，可更加真实有效地反应供应商得分的实际情况，避免由于评价准则之间的相互关系所带来的重复评价问题.

Abstract:

A new synthesis method of analytic hierarchy process (AHP), principal component analysis (PCA) and data envelopment analysis (DEA) was proposed to solve the vendor selection problem. And a case study was made on the method. The study result was compared with those by synthesis method of AHP and DEA. The result shows that the synthesis method can effectively eliminate the data redundancy and it can avoid overlapping evaluation caused by principle co relationship.
