Abstract: As a tool, Comprehensive Evaluation based on fuzzy matter-element model provides a way to calculate risks. This paper introduces the common theory of fuzzy matter-element model evaluation, puts up general procedures of risk evaluation based on fuzzy matter-element model evaluation, and establishes model of fuzzy matter-element model risk evaluation as well as comprehensive evaluation method based on fuzzy matter-element model. This paper, through a real project, analyses risks exist in the project of Caiyuanba Bridge in Chongqing from the view of proprietor with fuzzy matter-element model evaluation applied, and the results verifies the superiority and feasibility of the method and its good efficiency in project risk management.

Abstract: It is difficult to evaluate the performance of the different companies feasibly and fairly only depending on experts. An evaluation model based on TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) is built to solve this problem. In this model, the method of data processing and the evaluation algorithms are analyzed detailed. By means of the evaluation model, eight electric power supply bureau of Chongqing are evaluated in this paper, and the results show feasibly and reasonably. [Copyright &y& Elsevier]
