Managing RCM System Safety Case in an Integrated Database Environment

摘要

This paper presents the challenges for development and maintenance of the safety case for electrical, electronic andprogrammable electronic systems (E/E/PES) for safety-critical applications. An electronic Remote ConditionMonitoring (RCM) system is taken as a show case to demonstrate the elements of a safety case from concept,requirements and design to implementation, test, integration and transition to use. This reviews the techniques thatmay be used to manage safety issues at different phases of the project namely:a) Safety case data models such as Goal-Structuring Notation (GSN) to assist with the top-down planning ofthe safety goals, strategies, assumptions, models and context as well as arguments and evidenceb) Preliminary hazard analysis and the structure of a hazard log, its population and managementc) Compliance with safety regulations and safety standardsd) Full traceability and audit traile) Management information containing safety risk matrix as a summary of risks to be managed as the projectprogresses from one phase to another.
