摘要: 使用可用度是军用飞机重要的可靠性维修性保障性RMS(Reliability, Maintainability and Supportability)顶层参数.为了确定合理有效的使用可用度,根据论证阶段的实际情况,综合考虑军用飞机任务需求、初始使用和保障方案以及相似装备的RMS指标等信息,利用Monte-Carlo方法和排队论构建模型.对仿真过程中的任务开始、故障时刻、维修时间的抽样进行了分析,给出了抽样公式.以军用飞机RMS指标和使用保障方案作为仿真输入,反复迭代计算获得一族使用可用度与RMS参数的关系曲线,再综合权衡获得合理的使用可用度和相关RMS指标.给出了可靠性仿真的算法流程和相关的计算公式,并以案例验证了该方法的可行性.仿真模型具有通用性,可根据实际情况修改统计公式,满足不同参数的论证需求.

Abstract: Operational availability (AO) is an important top parameter of military airplane RMS(reliability, maintainability and supportability). In order to obtain reasonable and valid AO, based on characters of demonstration stage, a simulation model using Monte-Carlo method and queue theory was constructed by integrating the mission requirements, initial operations and support concept of military airplane and RMS data from similar systems. The sample methods of mission start, failure time and repair time were analyzed, and the sample formulas were presented. The model requires military airplane RMS data and operation maintenance scheme as input data, and calculates iteratively a family of relative curves between AO and RMS parameters. Based on analyzing the curves synthetically, the reasonable results could be obtained. The algorithm processes of reliability simulation and relative formulas were presented, and the method was verified by a case as well. The simulation model has general-duty character and can be used for different parameters demonstration by modifying the statistical formulas.
