Abstract

Features of software as a component of instrumentation and control (I&C) systems are analyzed. Attention is paid to the importance of functions performed by software and hazards of such software. Requirements for characteristics of software as a component of I&C systems are analyzed. Different regulatory documents are considered in order to disclose common approaches to the use of dedicated software and off-the-shelf software components. Classification of software, as well as classification of requirements, is described. Criteria of selection and structuring of requirements, as well as criteria for software verification, are defined. As long as the characteristics of software components directly depend on the quality of the processes of software development and verification, requirements for software life cycle processes are considered.
核电厂重要安全控制系统软件产品和流程要求
分析了软件作为仪表与控制系统组成部分的特点。注意软件功能的重要性和软件的危害。分析了作为测控系统组成部分的软件对其特性的要求。考虑不同的监管文件,以披露使用专用软件和现成软件组件的通用方法。描述了软件的分类,以及需求的分类。定义了选择和构建需求的标准,以及软件验证的标准。只要软件组件的特性直接依赖于软件开发和验证过程的质量,就应该考虑软件生命周期过程的需求。
