An Improved Multilevel Fuzzy Comprehensive Evaluation to Analyse Engineering Project Risks

摘要

This paper has carried out research in the risk identification of engineering projects. To overcome the problem of over reliance on expert's subjective judgment in the traditional risk identification, this paper develops a multilevel generalized fuzzy comprehensive evaluation mathematics model for risk identification Through iterative algorithm of AHP analysis, the model considers fully the sub project in risk analysis, then it combines expert's subjective judgment with objective quantitative analysis, and distinguishes the risk through identification models.. The concrete method of multilevel generalized fuzzy comprehensive evaluation is probed. Using the index weights to analyze project risks is discussed in detail. This method can help developers select the appropriate project so as to bring about positive influence on economy, society and environment.
