Dynamic Comprehensive Evaluation Using Semi-Partial Subtraction Set Pair Potential: Method and Application

Abstract

Addressing the issue of absolute evaluation conclusions generated by dynamic comprehensive evaluation methods, this paper proposes a novel approach based on Semi-Partial Subtraction Set Pair Potential (SP-SSPP). Firstly, the method determines the grade intervals by calculating the grey relational degree between the ideal point of evaluation values and their geometric mean. Secondly, the evaluation values and grade intervals form a set pair system characterized by certain-uncertain relationships. The state and development trend of this set pair system are then analyzed using SP-SSPP to derive comprehensive evaluation values and rankings. The utilization of non-discrete grade intervals effectively avoids the "either-or" evaluation conclusions inherent in traditional comprehensive evaluation methods. This characteristic enables the method to effectively guide the evaluated entities towards sustained and substantial development. Finally, the validity of the proposed method is demonstrated through a case study.
