摘　　要：为了使用于建筑施工绿色风险管理的资源实现优化配置,风险排序十分必要。完成建筑施工绿色风险因素的识别后,为克服衡量风险的属性不全面、排序方法过于单一的局限性,同时考虑到问题的模糊性与不确定性,从概率、损失、不可控制性、紧迫性四个维度以直觉三角模糊数描述相应风险因素,并利用逼近于理想灰关联投影的多属性决策方法,结合灰色系统理论、TOPSIS和矢量投影方法对风险因素进行排序,结合实例验证了该排序模型的实用性,为后续风险管理提供参考。In order to optimize distribution of resources used for green risk management in construction,risk ranking is of great necessity.To overcome the incompleteness of attributes used to characterize risks and simplification of ranking approaches,green risk factors in construction are identified.Taking fuzziness and uncertainty into account at the same time,the relevant risk factors are characterized with intuitionistic triangular fuzzy numbers from four dimensions：probability,damage,uncontrollability and urgency.Furthermore,an algorithm of multi-attribute decision making based on similarity to ideal grey relational projection,which combines grey system theory and TOPSIS with vector projection,is used to order risk factors,making references for subsequent risk management.Finally,the practicality of this model is validated through case analysis.
