Research on the Model of Public Project Performance Evaluat ion-A Case Study of Water Environment Project

Abstract

In order to improve urban water environment project investment benefit, it is necessary to evaluate the performance of the project systematically and comprehensively. The paper takes advantage of Dempster- Shafer (D-S) evidential theory and triangle whitening function in data processing and data integration to construct the evaluation model. Firstly, the triangular fuzzy number is used to determine the indicator weight. Then the grey clustering matrix is constructed to determine the level of each criterion of the urban water environment project. Finally, the paper identifies the grey class of project performance evaluation based on D- S evidence theory and determines the integrated performance level of project.
