摘　　要：为实现在用电梯的动态分级监管,提出了在用电梯系统风险评价方法.首先,通过分析现行标准和研究现状,确立了在用电梯系统风险评价的基本程序,包括准备工作、风险评价、降低风险和生成文件等四个方面.其次,通过对电梯设备、相关人员、运行管理以及使用环境进行风险分析和风险评定,确定评价单元,找出危险状态;综合运用专家打分法和层次分析法,建立了在用电梯系统风险评价模型.对电梯部件的风险评价,采用模糊评价方法确定单因素危险状态的风险等级,并对单因素风险的概率等级和严重程度进行量化处理,得到电梯部件多因素综合风险评价值.通过该方法,可以实现对一定区域内的在用电梯进行动态分级监管,以优化监管资源配置,提高监管工作效率.To carry out dynamic classification regulation of in-service elevator,the elevator system risk assessment method was proposed.Firstly,a basic procedure of the elevator system risk assessment,including four aspects of preparation,risk evaluation,risk reduction and generated document,was established by analyzing current standards and research status.Then,evaluation units were confirmed and hazardous situations were found by analyzing and assessing the risk of elevator equipment,the associated personnel,operations management and service environment.A risk assessment model of existing elevator system was established by the expert scoring method and the analytic hierarchy process.As for the risk assessment on elevator parts,the risk grade of single factor hazardous situation was confirmed by fuzzy assessment method.The comprehensive value of multi-factor risk assessment of elevator parts was obtained by quantizing the probability and severity of single factor risk.Through the above method,dynamic classification regulation of existing elevators in certain area can be realized to optimize regulatory resources allocation and improve the efficiency of supervision.
