基于多属性决策TOPSIS方法对模糊环境下建筑工程项目的风险评估问题进行研究。首先对建筑工程项目的风险因素进行分析，构建建筑项目风险属性集，并给出各因素的权重。然后应用TOPSIS方法对模糊环境下的项目风险进行评估，并对备选项目进行排序。案例详细说明了相关方法的具体应用过程，验证了风险属性集和方法的有效性和实用性，对建筑工程项目的风险管理具有一定的实践和理论价值。 The paper presents risk assessment of construction objects under the fuzzy environment based on multi-attribute decision making method of TOPSIS. Firstly, while the risk factors of construction engineering project are analyzed, the risk criteria set is established clearly. Then the TOPSIS me-thod is applied to assess the risk of project with fuzzy information, and the ranking of the alterna-tives can be obtained according to the assessment results. Lastly the example illustrates the de-tailed application process of fuzzy TOPSIS, and verifies the effectiveness and feasibility of the proposed risk criteria set and TOPSIS method, and shows that the research has some practical and scientific value.
