    摘要:

    本文提出了一种基于熵值的装备维修性综合评价模型,该模型包括评价指标的熵值度量模型、装备维修信息结构图和行为控制图以及基于熵值的评价指标聚合模型等3个方面。本研究首先在分析装备维修一般过程和维修性评价内容的基础上,构建了定性指标和定量指标相结合的装备维修性评价指标体系,分析了维修任务复杂度、维修保障复杂度和基于熵值的维修效果的涵义;其次,给出了定性指标的熵值、定量指标的熵值以及基于权值的装备维修性熵值等计算方法;最后,给出一个装备维修性熵值评价的算例。算例结果表明,所提方法能够结合综合维修任务、维修保障和维修效果等多种影响因素进行装备维修性评价,不仅可以根据熵值大小对装备维修性水平进行高低排序,还可以分析影响装备维修性水平的瓶颈因素。

    Abstract:

    This paper proposes a comprehensive entropy-based evaluation model of equipment maintainability. Based on an analysis of the general equipment maintenance process and the content of maintainability assessments, an equipment maintainability evaluation index system, which combines qualitative and quantitative indexes, is constructed. The definition of maintenance task complexity, maintenance complexity guarantees, and entropy-based maintenance effects are analyzed. A comprehensive evaluation model of equipment maintainability is established by incorporating three factors which include an entropy-based measurement model of evaluation indexes, an equipment maintenance information structure diagram and behavior control diagram, and an aggregation model of evaluation indexes based on entropy. In addition, the entropy calculation methods for the qualitative index, quantitative index, and weighted equipment maintainability are presented. Finally, this paper provides an example of a comprehensive entropy-based evaluation of equipment maintainability. The results of the case demonstrate that the proposed methods are reasonable and feasible, and they can effectively integrate maintenance tasks, maintenance guarantees, maintenance effects, and other influencing factors for equipment maintainability assessments. This approach can be used to compare or sort the equipment maintainability level based on entropy, as well as to analyze bottleneck factors affecting equipment maintainability.
