| 中文摘要: |
| 考虑到专业背景和知识结构差异性导致专家的重要程度不同，此处提出一种基于三角模糊数及其相对相似度的安全评价模型。首先查阅文献并结合装配式建筑施工特点，从人员、材料设备、管理、技术、环境 5 个维度构建评价指标体系。其次，请专家给出指标语义评价等级和指标权重语义评价等级，依据对应关系将其转化为三角模糊数，用三角模糊数间的相对相似度衡量各专家平均贴近度，继而确定各专家综合权重。最后，集结评价数据，得到总体安全评价结果。为验证模型的可行性，将其应用于某装配式建筑中，结果表明该项目安全等级为“良”，与工程实际安全状态基本相符。该方法一定程度上提高了安全评价的科学性、准确性。 |

| Considering the different importance of experts due to the variability of professional background and knowledge structure，a construction safety evaluation model based on triangular fuzzy number theory and the relative similarity is proposed. Firstly，the evaluation index system was constructed from five dimensions：personnel，material and equipment，management，technical and environment by literature review and combining the characteristics of prefabricated building construction.Secondly，The semantic and weighted semantic evaluation levels of indexes are given by the experts，which are transformed into triangular fuzzy numbers according to the correspondence. The average closeness of each expert is measured by the relative similarity between the triangular fuzzy numbers，hence the comprehensive weight of each expert is determined. Finally，the safety evaluation results are obtained by aggregating the evaluation data. The model was applied to a prefabricated building project to verify its feasibility. The results show that the safety level of the project is good，which is basically consistent with the status.The method makes the safety evaluation of prefabricated buildings more scientific and accurate. |
