装备平均修复时间验证方法研究综述

Review on research of equipment mean time to repair demonstration methods

维修性验证是装备维修性工作的重要组成部分,平均修复时间(mean time to repair,MTTR)是维修性定量要求验证的主要参数。本文从国内外装备MTTR验证标准和手册发展情况以及装备MTTR验证常用方法两个方面综述了MTTR验证方法的国内外研究进展。介绍了美国国防部、国际电工委员会和国内相关机构颁布的MTTR验证标准和手册的发展情况,分析了标准和手册中的MTTR验证方法。总结归纳了装备MTTR验证的常用方法及应用情况,包括基于实物装备的验证方法和基于虚拟现实的验证方法。在此基础上概括了装备MTTR验证方法的研究特点,展望了未来的研究方向,并给出了研究建议。

Maintainability demonstration is an essential part of equipment maintainability work.Mean time to repair(MTTR)is the main parameter for the demonstration of the quantitative maintainability requirement.The MTTR demonstration methods research is reviewed from the aspects of the development of MTTR demonstration standards and handbooks at home and abroad and common methods for MTTR demonstration.The MTTR demonstration standards and handbooks issued by the U.S.Department of Defense,International Electrotechnical Commission and China related agencies are introduced.The MTTR demonstration methods in the above standards and handbooks are analyzed.The common methods for equipment MTTR demonstration,including physical equipment-based and virtual reality-based demonstration method,and their applications are discussed and concluded.In addition,the research features and future directions of the MTTR demonstration methods are suggested,the developing advices are proposed.
