摘　　要：针对起重机等机电设备电气系统的功能安全评估,在采用专家评估法确定权重的过程中可能存在主观性过强的问题,且固定权重不能表现数据中的某些异常参数对系统的影响,文中提出了对权重进行动态的调整,基于层次分析和聚类分析法来确定静态权重,在确定权重的过程中能保证其一致性,采用不同的权重动态调整方法,对超出预警值和极限值的输出特征参数进行突出显示。通过实例计算,根据每项参数的分数和调整后的权重得出相应综合分数,划分风险等级。For the safety assessment of electrical system of mechanical and electrical equipment such as cranes,there may be subjective problems in the process of determining weights by expert assessment method,and the fixed weights can’t reflect the influence of some abnormal parameters in the data on the system.This paper proposes to dynamically adjust the weights and determine the static weights based on analytic hierarchy process and cluster analysis method,which can ensure their consistency in the process of determining weights.Different dynamic weight adjustment methods are used to highlight the output characteristic parameters that exceed the warning value and the limit value.Through example calculation,the comprehensive score is determined according to the score of each parameter and the adjusted weight,and then the risk level is divided.
