【摘要】：绿色施工风险评价对建筑业可持续发展具有重要作用.首先结合绿色建筑与绿色施工评价体系,建立了绿色施工风险评价指标.其次改进了Vague群决策方法,建立了绿色施工风险评价模型,运用层次分析法确定二级指标权重,根据二级指标权重和相应Vague值确定各专家的一级指标Vague值;对专家权重进行了改进,同时考虑专家主观权重和专家的评价意见及评价矩阵的一致性,避免了专家权重确定的主观性.最后利用Vague集计分函数对风险因素排序,根据得分和专家评价意见的集结得出绿色施工风险等级,克服了层次分析法权重确定的主观性和传统模糊集易损失中间值的不足.实例结果表明该方法能够更好地解决工程绿色施工风险评价问题.
[Abstract]:Green construction risk assessment plays an important role in sustainable development of construction industry. Firstly, combining green building and green construction evaluation system, the evaluation index of green construction risk is established. Secondly, the Vague group decision-making method is improved, the green construction risk evaluation model is established, the second-level index weight is determined by AHP, and the first-order index Vague value of each expert is determined according to the second-level index weight and corresponding Vague value. The expert weight is improved, and the subjective weight of the expert is considered, the evaluation opinion of the expert and the consistency of the evaluation matrix are taken into account, and the subjectivity of the expert weight determination is avoided. Finally, the Vague set scoring function is used to rank the risk factors, according to the accumulation of scores and expert evaluation opinions, the green construction risk grade is obtained, which overcomes the subjectivity of determining the weight of AHP and the deficiency of the traditional fuzzy set which can easily lose the intermediate value. The example shows that the method can solve the problem of green construction risk evaluation better.
