The present invention provides a hazard analysis method for minimizing the possibility of omission in hazard identification and more systematically analyzing the hazard in the hazard analysis of an elevator control system. Provided is a hazard analysis method of a software control system, which is performed by a computer and is based on a system theoretic process analysis (STPA). The method of the present invention comprises the following steps of: identifying attributes and functional requirements of a 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 displays a hierarchical relationship of a control flow between the tasks; identifying at least one hazard related to the system based on the specification; and writing safety constraints related to the system based on the identified 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.
