ABSTRACT

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 method is applied to assess the risk of project with fuzzy information, and the ranking of the alternatives can be obtained according to the assessment results. Lastly the example illustrates the detailed 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.

3. 模糊环境下基于TOPSIS的项目风险评估

TOPSIS法将方案集中同时距理想解最近，且距负理想解最远的方案作为问题解。本文利用TOPSIS法思想，给出建筑工程项目方案风险评估的算法步骤：

Step 1：形成初始决策矩阵，其中为风险属性数量，为项目方案数量。

Step 2：对初始决策矩阵进行规范化 [10] ，得到规范化决策矩阵，具体方法如下。

,为效益型值，为损失型值 (3)

Step 3：根据文献 [10] 中关于运算“”的定义，计算规范化加权评估值

Step 4：确定正理想解和负理想解，方法如下。
