摘要
针对当前电梯安全评价指标选择单一、赋权不严谨以及评价方法缺乏系统性的现状,提出基于多重组合赋权和灰色关联分析法的电梯安全评价模型。首先采用层次分析理念构建安全评价体系,包含4个一级指标和32个二级指标;然后采用模糊层次分析法(FAHP)、熵权法(EWM)分别计算指标的主观和客观权重,引入距离函数法、最小信息熵法及均值法多重求得综合权重;最后采用灰色关联分析法计算参评方案与最优方案的关联度,得到评价结果。实例验证,该方法得出的结论与实际情况相吻合,可用来有效评价电梯的真实安全水平,对电梯的安全使用管理有一定参考意义。
According to the current situation of elevator safety evaluation single selection index,loose weighting and nonsystematic evaluation methods,a elevator safety evaluation model based on multiple combination weighting and grey correlation analysis method is proposed.Firstly,the safety evaluation system is constructed with the analytic hierarchy process,including 4 primary indicators and 32 secondary indicators.Secondly,fuzzy analytic hierarchy process(FAHP)and entropy weight method(EWM)are used to calculate the subjective and objective weights of the index respectively,and the multiple comprehensive weights are obtained by distance function method,minimization principle entropy method and averaging method.Finally,the grey correlation analysis method is used to calculate the correlation degree between the participating scheme and the optimal scheme,the evaluation results are obtained.The example shows that this method can effectively evaluate the real safety level of elevator,which is consistent with the actual situation.It also has certain reference significance for the safe use and management of elevator.
