可靠性 可维护性和可持续性术语和定义

[中文适用范围]： 对可靠性、可维护性和可持续性 (RMS) 工作有用的基本术语和定义词汇表。大多数工程技术中使用的术语往往是物理特性，例如速度、转速和燃料消耗。虽然它们可能需要非常仔细的定义和对其测量方式的控制，但术语本身不会有不同的解释。然而，可靠性、可维护性和可持续性 (RMS) 使用的术语有多种定义方式和多种解释。当试图将一个系统的性能与另一个系统进行比较时，对单个术语的多种定义会产生问题。为了消除混淆，我们进行了文献检索，列出了当前和过去的 RMS 术语和定义。文献检索包括来自美国军方、英国军方、北约、SAE、IEEE、NASA、ISO、大学研究和其他出版物的输入。 [外文原描述]： A glossary of basic terms and definitions useful for working in reliability, maintainability, and sustainability (RMS).The terms used in most engineering technologies tend to be physical characteristics such as speed, rate of turn, and fuel consumption. While they may require very careful definition and control of the way in which they are measured, the terms themselves are not subject to different interpretations. Reliability, maintainability, and sustainability (RMS), however, use terms that are defined in a variety of ways with multiple interpretations.The variety of definitions given to a single term creates problems when trying to compare the performance of one system to another. To eliminate the confusion, a literature search that listed current and past RMS terms and definitions was conducted. The literature search included input from the U.S. military, UK military, NATO, SAE, IEEE, NASA, ISO, university research, and other publications. The object was to determine the common definition of reliability terms from a variety of sources. It is accepted that some of the definitions may be unique because of the nature of the mission, but it is the strong conviction of the government and industry practitioners who make up the SAE Reliability Committee under the G-11 Division that there should be some fundamental definitions used for all hardware systems.Accordingly, in October of 2003, there were discussions to revise the current AIR4896 that was published in 1995. It is understood by individuals who participated in this project that future editions will update terminology as developments are made within the RMS community. Due to the complexity and nature of software reliability, we have specifically excluded “software reliability” terms from this edition. Future updates of this document will continue to reflect the converging of defense and commercial technology and StandardDetails.Cross Reference:
