摘　　要：文中针对立体停车设备在系统状态评价时权重难以确定的问题,引入改进熵权法达到评价过程中的主客观权重合理确定。以垂直循环式立体停车设备为例,建立了系统状态评价模型;引入Logistics激活函数对信息熵进行改进,并结合层次分析法的主观权重,形成融合主客观的综合权重;最后以某单位在役垂直循环立体停车设备为例,利用提出的方法开展系统状态评价,并将算得结果与组合权重法、层次分析法进行对比,验证了提出方法的有效性和可行性。Considering that it is difficult to determine the weights in the state evaluation of stereo parking equipment system,an improved entropy weight method was introduced to ensure the reasonable determination of subjective and objective weights in the evaluation process.Taking vertical circulating parking equipment as an example,a system state evaluation model was established.Logistics activation function was introduced to improve information entropy,and subjective weights of analytic hierarchy process were combined to covering subjective and objective weights.Finally,taking the in-service vertical circulation parking equipment of a unit as an example,the system state was evaluated by the proposed method,and the results were compared with those of the combined weight method and analytic hierarchy process,which verifies the effectiveness and feasibility of the proposed method.
