Abstract: This paper has carried on research to the risk identification of the project．To overcome the question that depends too much on expert's subjective judgement in traditional risk identification，this paper structure the comprehensive evaluation mathematics model of the risk identification of project．Through iterative algorithm of AHP analysis．make surc the important degree of the sub project in risk analysis，then combine expert's subjective judgement with objective quantitative analysis，and distinguish the risk through identification models．In the end state the application ofthis method through the instance．

Key words: risk identification, fuzzy Comprehensive evaluation：AHP analysis

摘要： 针对传统的风险辨识中过渡依赖于专家主观判断的问题，构建了工程项目风险辨识的综合评价数学模型．通 过层次分析法的迭代算法，确定子项目在风险分析中的重要程度，将专家主观判断与客观定量分析相结合，通过 辨识模型进行风险辨识．最后通过实例说明了本方法的应用．
