Provided is a method for analyzing a hazard of a software control system based on a system theoretic process analysis (STPA), which is performed by a computer. The method according to the present invention includes the steps of: identifying attributes and functional requirements of the system; analyzing tasks of the system based on the identified attributes and functional requirements; specifying a relationship between the tasks according to a predetermined notation for the analyzed tasks, wherein the predetermined notation shows a hierarchical relationship of a control flow between the tasks; identifying one or more hazards associated with the system based on the specification; and writing safety constraints on the system based on the identified hazards. Accordingly, the present invention can minimize missing possibility in the identification of the hazard and systemically and accurately analyze the hazard.

    컴퓨터에 의해 수행되며, STPA(System Theoretic Process Analysis)에 기초한, 소프트웨어 제어 시스템의 위험(hazard) 분석 방법이 제공된다. 본 발명의 방법은, 시스템의 속성 및 기능 요구사항들을 식별하는 단계; 식별된 속성 및 기능 요구사항들에 기초하여, 시스템의 태스크들을 분석하는 단계; 분석된 태스크들에 대해, 태스크들 간의 관계를 소정의 표기법에 따라 명세하는 단계 - 소정의 표기법은 태스크들 간의 제어 흐름의 계층적 관계를 보여줌 -; 명세에 기초하여, 시스템에 관한 하나 이상의 위험을 식별하는 단계; 및 식별된 위험에 기초하여, 시스템에 관한 안전성 제약사항을 작성하는 단계를 포함한다.
