Ensuring System Safety and Resiliency for Mission-Critical Systems during the Operations and Maintenance Phase

Ensuring system safety and resiliency of mission-critical systems throughout their life cycle is a continuous process. This paper delves into enhancing system safety during the operations and maintenance phase, a period susceptible to latent faults, design and implementation errors, worn-out equipment, and human errors. The author proposes a three-pronged approach encompassing service thread-based Failure Mode and Effects Analysis, machine learning techniques trained on historical and real-time operational data, and periodic analysis for operations and maintenance procedures. By integrating these strategies, the paper aims to bolster system resilience, mitigate potential system hazards and risks, and minimize system outages of mission-critical systems, ultimately ensuring uninterrupted operations.
