模块通用化对雷达装备群可靠度及可用度的影响

Impact of Module Generalization on Reliability and Availability of Radar Equipment Group

为量化分析通用化程度与可靠度和可用度之间的关系,根据雷达兵部队的特点定义装备群概念,并假设雷达群中所有的雷达模块不可修复、部分模块可通用,采取模块更换的保障方式,通过对模块通用化程度、装备群系统整体的可靠度和可用度分析,推导出模块通用化程度分别影响雷达装备群可靠度和可用度的数学模型.最后通过算例仿真得出:装备群模块通用化程度D对可靠度和可用度有一定影响,当D从0.1上升到0.6时,可靠度和可用度分别从0.52上升到0.78和从0.917上升到0.961.

To qualitatively analyze the relation between the generalization degree and the equipment reliability and availability,the idea of equipment group was defined in terms of the features of radar troops.Assumed that all the modules in radar group can not be repaired and the partial modules can be for general purpose use,the math model of impact of module generalization degree respectively on the reliability and availability of radar equipment group was derived by taking the support mode of module replacement and analyzing the module generalization degree,and the reliability and availability of the entire equipment system.Finally,by simulating examples,it can be seen that the module generalization degree D of equipment group has a certain impact on its reliability and availability,and the reliability and availability increases respectively from 0.52 up to 0.78 and from 0.917 up to 0.961 when D increases from 0.1 up to 0.6.
