基于BWM群决策赋权与FMEA的风险评估方法*

为实现BWM群决策评估结果的有效聚合，构建1种基于输入数据的决策者赋权法。该赋权法基于输入数据的一致性水平，衡量决策者对评估对象的认知程度并确定权重，使BWM能够应用于群决策过程，从而构建基于BWM群决策赋权和FMEA的风险评估法。通过邮轮玻璃幕墙风险评估的实例验证该方法，并通过序数一致性分析方法的有效性。研究结果表明:在客观数据缺乏而依赖专家主观经验评估的情况下，该方法能够降低评估能力较低个体对团队评估结果的影响。

Risk assessment method based on BWM group decision-making weighting and FMEA

In order to realize the effective aggregation of group decision-making evaluation results with the best-worst method (BWM),a decision-maker weighting method based on input data was proposed.Based on the consistency level of input data,this method measured the cognition degree of decision-makers on the evaluation objects and determined the weight,so that the BWM could be applied to the process of group decision-making,thus a risk assessment method based on the BWM group decision-making weighting and failure mode and effects analysis (FMEA) was constructed.The method was validated by an example of risk assessment on the cruise glass curtain wall,and the validity of the method was analyzed by ordinal consistency.The results showed that the method could reduce the influence of individuals with poor evaluation ability on team evaluation results when the objective data were lacking and the experts’ subjective experience evaluation was relied on.
