Requirements Engineering을 적용한 ISO26262 대상 제품의 요구사항 분석에 대한 Case Study

The standard ISO 26262 is an adaptation of the Functional Safety standard IEC 61508 for Automotive Electrical /Electronic Systems. This paper provides systematic approach to perform the development of functional safety requirement using requirements engineering related method in order to comply with ISO26262 "Part3. Concept phase,"Part4. system leveland describes how to efficiently integrate functional safety requirements and general functional requirements. First of all, goal-driven requirements development approach which is based on requirements engineering method will be applied to combine safety goal derived from HARA (Hazard Analysis Risk Assessment) and system goal of system functional requirements. Next, it present how to efficiently specify system functional safety requirements using requirements engineering related method which includes safety measure to minimize potential risk of system. Presented requirements engineering approach and method will be explained in detail with case study which is applied ISO26262 target product. Those concrete approaches facilitate the development of functional safety requirements without trial and error and contribute to concentrate on development of safety critical system.
