功能安全研发的方法论研究

Research on methodology of functional safety research and development

为促进功能安全在安全领域的应用与发展,丰富功能安全研究的理论体系,进行了功能安全的方法论研究。重构了功能安全定义,从4方面解释其内涵,厘清其研究对象;论述了功能安全的作用机理,即通过建立安全相关系统(SRS)维持系统安全,从理论和技术应用2个层面说明功能安全研究内容;概括了功能安全研究须遵循的5个原则,以及进行功能安全研究适用的4种方法;提出进行功能安全研究的一般程序,说明每个步骤的具体内容及实施方法或依据。研究结果表明:功能安全方法论是功能安全作用机理、研究内容、研究原则与方法以及研究程序等结合而成的条理化的、具有一定指导意义的理论体系。

To promote the application and development of functional safety in the field of safety,and enrich the theory system of functional safety research,the research on the methodological of functional safety was conducted.The definition of functional safety was reconstructed,and its connotation was explained from four aspects,then its research objects were clarified.The action mechanism of functional safety was discussed,namely maintaining the system safety through establishing the safety related system(SRS),and the research contents of functional safety were explained from two levels of theory and technology application.The five principles needing to be followed in the functional safety research and the four methods being suitable to carry out the functional safety research were summarized.The general procedure of conducting the functional safety research was put forward,and the specific contents and implementation methods or basis of each step were explained.The results showed that the methodology of functional safety is a systematic and instructive theory system that combines the action mechanism,research contents,research principles and methods,research procedures of functional safety,and so on.
