针对坦克火控系统状态评价过程中存在的主观性较大、结果不够精确等问题,研究了基于熵权法的火控系统健康评价方法。在建立健康评价指标体系的基础上,构建了健康指数模型。按照指标属性,对不同量纲的指标进行归一化处理,采用熵权法计算模型中各指标对系统健康状况影响的权重值。最后采用该方法对某型坦克火控系统进行评价。结果表明,稳定性指标是影响火控系统总体性能的重要指标。评价结果具有较高的可信度,可为火控系统的使用及维护提供依据。

In order to solve the problems exiting in the condition assessment of tank fire control system, such as bigger subjectivity and less accuracy, the health assessment of fire control system based on entropy weight method is studied. Health index model is established on the basis of index system of health assessment. According to the index attributes, the indexes with different dimensions are normalized. The weight of each index is computed by using entropy weight method. Finally, the method is used to assess the health condition of tank fire control system. The assessment results show that stability indexes are the important one that has influence on the general performance of fire control system. It is also proved that the assessment result is reliable and is able to provide some guidelines for the usage and maintenance of fire control system.
