一种基于D-S理论的自评系统ER改进方法

The Improvement and Application of Evidential Reasoning Approach in Self-assessment System Based on Quality Award

针对质量奖自评系统中评分方法的主观性问题,本文基于D-S理论,提出了一种新的证据推理方法,并证明该方法完全满足Y ang等人提出的任何证据合成过程必须满足的四个公理。通过自评实例运算,进一步验证了该方法的有效性和合理性。

Aimed at the subjectivity of evaluation approach used in self-assessment system based on quality award, this paper proposes a revised evidential reasoning（ER） approach based on D-S theory, and proves that the new approach completely satisfy the synthesis axioms which have been proposed by Yang and Xu for which any rational aggregation process should grant. A numerical example in self-assessment is further used to illustrate the validity and rationality of the new approach.
