基于改进FMEA法的装配式混凝土建筑建造质量风险评价

为了有效分析装配式混凝土建筑关键建造质量风险因素,提高相关方质量管理水平,对建造质量风险因素进行收集归纳,建立装配式混凝土建筑建造质量风险评价指标体系,提出基于模糊TOPSIS和变权法改进的FMEA风险评价模型。考虑装配式混凝建筑风险指标评价要素状态值的多变性,将惩罚型变权法引入评价要素客观权重确定中,建立各风险指标评价要素的加权规范化矩阵,再利用TOPSIS逼近理想解的原理进行风险排序,得到风险优先等级,并结合实例验证该方法的可行性和可操作性,从而为装配式混凝土建造质量风险管理提供一种新思路。

Construction Quality Risk Assessment of Prefabricated Concrete Buildings Based on Improved FMEA Method

To effectively analyze the key construction quality risk factors of prefabricated concrete buildings and improve the quality management level of relevant components，this study collects and summarizes the construction quality risk factors and establishes a quality assessment index system for the construction of prefabricated concrete buildings. An improved FMEA risk assessment model based on fuzzy TOPSIS and variable weight method is proposed. Given the variability of the state values of the evaluation indicators of prefabricated concrete buildings’ risk indicators，the penalty-type variable weight method is applied to evaluate of the objective weights of the indicators. The weighted normalization matrix of the risk indicator evaluation is then used to approximate the ideal solution by TOPSIS to rank the risks and obtain the risk priority level. Finally，the feasibility and operability of the method is verified by an example of prefabricated concrete building，which provides a new idea for the quality risk management of fabricated concrete construction.
