可靠性要求的证明 可靠性案例

[中文适用范围]： 本国际标准提供了关于可靠性案例（dependability case）内容和应用的指导，并确立了准备可靠性案例的一般原则。本标准是在一个基本项目背景下编写的，其中客户向供应商订购满足可靠性要求的系统，然后管理该系统直至其退役。根据需要在其他情况下，本标准中提供的方法可进行修改和适应。可靠性案例通常由客户和供应商制作，但也可由其他组织使用并更新。例如，认证机构和监管机构可能会检查提交的案例以支持其决定，系统用户可能会更新/扩展案例，特别是当他们将系统用于不同目的时。 [外文原描述]： IEC 62741:2015 gives guidance on the content and application of a dependability case and establishes general principles for the preparation of a dependability case. This standard is written in a basic project context where a customer orders a system that meets dependability requirements from a supplier and then manages the system until its retirement. The methods provided in this standard may be modified and adapted to other situations as needed. The dependability case is normally produced by the customer and supplier but can also be used and updated by other organizations. For example, certification bodies and regulators may examine the submitted case to support their decisions and users of the system may update/expand the case, particularly where they use the system for a different purpose. Keywords: dependability, reliability, availability, maintainability, supportability, usability, testability, durability.
