摘要: 平均修复时间(MTTR,Mean Time To Repair)作为一个重要的维修性定量指标,目前其预计方法及算法立足于大量的试验结果和经验估计.通过对任务—装备—维修组成的面向任务的队列模型的研究,将任务需求、武器系统的可靠性及维修性综合考虑,针对故障率和修复率均服从指数分布的可修系统,建立了一种基于M/G/1可修排队模型的武器系统MTTR的模型,并给出了定量预计方法.此模型符合基于可靠性基础上的维修理论的基本结论,避免了设计初期对大量维修统计数据的依赖,为订购方在装备采购中提出维修性定量的要求提供了依据.

Abstract: As an important quantificational index for maintainability, the predication method and algorithm of mean time to repair (MTTR) are always dependent on experimentation and experience. Through the queue research of mission-furnishment-maintenance oriented to uni-mission, the MTTR model was to be established based on M/G/1 for repairable system which aim at the failure rate and repairable rate subjected to exponential rule, considering the mission requirement, reliability and maintainability. The corresponding quantitative method was also given. This model adhere to the basic conclusion which is drawn from maintainability theory based on reliability, and prevent from depending on a large quantity of statistical data at the beginning of design stage. The model and prediction method of MTTR can provide the quantitative maintainability index for purchaser on the condition of purchasing the weapon system.
