| Reliability engineering is an engineering field that deals with the study, evaluation, and life-cycle management of reliability: the ability of a system or component to perform its required functions under stated conditions for a specified period of time. |
可靠性工程是一个从事有关可靠性（系统或元件在规定的时间内和规定的条件下执行规定功能的能力）研究、评估和生命周期管理的工程领域。 |
| Reliability engineering is a sub-discipline within systems engineering. |
可靠性工程是系统工程内的一个子学科。 |
| Reliability is theoretically defined as the probability of failure, the frequency of failures, or in terms of availability, a probability derived from reliability and maintainability. |
可靠性在理论上被定义为故障概率、故障频率，或者从可用性方面讲，是源于可靠性和可维修性的概率。 |
| Maintainability and maintenance may be defined as a part of reliability engineering. |
可维修性和维修保养可以被定义为可靠性工程的一部分。 |
| Reliability plays a key role in cost-effectiveness of systems. |
可靠性在系统的成本效益方面发挥着关键作用。 |
| Reliability engineering for complex systems requires a different, more elaborate systems approach than for non-complex systems. |
用于复杂系统的可靠性工程需要一种不同的、比非复杂系统详细很多的系统方法。 |
| Reliability analysis has important links with functional analysis, requirements specification, hardware & software design, manufacturing, testing, maintenance, transport, storage, spare parts, operations research, human factors, technical documentation and work skill training. |
可靠性分析和功能分析、产品规格说明、软硬件设计、生产制造、测试、维修、运输、仓储、备件、经营研究、人为因素、技术文档和工作技能培训都有着重要的联系。 |
| Effective reliability engineering requires experience, broad engineering skills and knowledge from many different fields of engineering. |
有效的可靠性工程需要来至于许多不同工程领域的经验和广博的工程技术和知识。 |
| Reliability engineering is closely related to safety engineering and system safety, in that they use common methods for their analysis and may require input from each other. |
可靠性工程与安全工程和系统安全性密切相关，因为它们使用相同的方法来分析，而且可能需要彼此的信息。 |
| Reliability engineering focuses on costs of failure caused by system downtime, cost of spares, repair equipment, personnel and cost of warranty claims. |
可靠性工程注重于系统停机引起的故障成本、备件成本、维修设备成本、人员和保修成本。 |
| The focus of safety engineering is normally not on cost, but on preserving life and nature, and therefore deals only with particular dangerous system failure modes. |
安全工程的注重点通常则不在成本上，而是在保护生命和自然环境上，因此只涉及特定的危险系统故障。 |
| High reliability (safety) levels are also here the result of good engineering, attention to detail and almost never the result of re-active failure management (Reliability Accounting / Statistics). |
高可靠性（安全性）也是优良工程、注重细节的结果， 而几乎从来不是反应式故障管理的结果（可靠性计算/统计）。 |
| "Reliability is, after all, engineering in its most practical form" as once stated by James R. Schlesinger, Former US Secretary of Defense. |
美国前国防部长詹姆斯•R•施莱辛格曾经说过：“可靠性，说到底，是最具实践形式的工程”。 |
