The Application of Risk Analysis Based on the Gray Relational Analysis in Power Engineering Comprehensive Evaluation

Abstract

Combined with the characteristics of power engineering projects, the paper introduces a kind of theoretical model that leads gray relational analysis and risk analysis into AHP appraisal method. This article describes the application steps of the model by a case. This article's main focus is the membership of risk index and the index weight. In the risk comprehensive evaluation model, the paper adopts the risk analysis method and gray relational analysis method to determine the membership and the weight of risk index. This model is considered to be the virtue of the subjective weight and the objective one. It can improve the accuracy of the evaluation.
