Base operational unit corrective maintenance process modeling and simulation
-
摘要: 为分析评价基本作战单元修复性维修保障方案,准确计算故障修复时间,根据 系统工程建模思想,建立了基本作战单元站点间、站点内修复性维 修过程仿真模型,对其修复性维修活动进行了详细描述,提出了累积维修比、维修模式比和 拆卸率因子参数,为基本作战单元修复性维修过程的定量分析提供了度量方法,并根据 Monte Carlo仿真原理给出仿真算法,为型号工作人员进行保障性设计分析提供了理论方法和技 术手段,最后以某型飞机组成的基本作战单元为例,对其修复性维修保障方案进行仿真试验 验证,分析了修复性维修过程的改进对保障资源和维修时间的影响.Abstract: To analyze base operational unit(BOU) corrective maintenance stratagem and accurately calculate fault recovery time, BOU corrective maintenance proces s simulation models among depots was set up, the models in dep ot was also set up according to system engineering modeling ideology, BO U corrective maintenance activities was described. Accumulate maintenance rate(A MR), maintenance mode rate(MMR) and remove rate(RR) parameters were presented. M easurement methods based on the parameters were given via to which BOU corrective maint enance process was quantitatively analyzed. The simulation algorithm was m ade out according to Monte Carlo simulation method. Theory and technology means were offered to equipment designer in the supportability design and analysis wor king areas. The corrective maintenance concept(CMC) was validated in an airplane individual unit example making use of simulation tests. The effects to support resource and maintenance time was analyzed with the bettered CMC.
