Self-Healing Engineering Systems through Autonomous Fault Recovery Mechanisms

Abstract

With the increasing complexity, interconnection and continuous operation of modern engineering systems, System reliability, availability, and resilience have become fundamental requirements in such cases. Traditional fault management systems depend on human oversight and predefined recovery procedures, leading to significant downtime along with sluggish responses in the event of unexpected failures. An intriguing class of systems that improve the abilities mentioned above are self-healing engineering systems, where a system detects faults in its services as they happen through continuous monitoring or on-demand testing processes; analyses the root causes, and recovers from damage autonomously without human involvement. This work studies the resilient autonomous fault recovery mechanisms that improve complex engineering system operability. The approach offers a unified self-healing architecture that integrates continuous monitoring, fault detection, intelligent diagnosis, and automated decision-making and recovery capabilities. This system continuously monitors all the operational data coming from different engineering components via sensors and agents, capturing it in external logs. Abnormal condition detection based on advanced data analytics, AI and ML techniques can help in detecting abnormal system behaviour which potentially causes a failure before it significantly impacts the performance of your highly targeted systems. When a fault is detected, the data available for diagnosis will be analysed to determine what component in the system might have failed and how serious that failure potentially was. Depending on the diagnosis, an autonomous recovery mechanism chooses and performs action(s) such as service restart, component replacement/upgrade/load distribution/configuration reconfiguration. Detailed information about the recovery is used by requesting continuous feedback from it, allowing it to assess how effective its last step was and to choose suitable responses for future cases. The proposed self-healing framework aims to minimise system downtime, increase fault tolerance and operational reliability while reducing human intervention. The approach is capable of autonomous fault detection, diagnosis and recovery as well as continual adaptation for reliable operation in many different critical engineering environments, including industrial automation, aerospace systems, smart manufacturing, energy infrastructure-related applications, robotics and IoT-based applications, etc. Intelligent monitoring and self-recovery methods make it easier for engineering systems to tackle changes in operating conditions or disturbances from failures. In summary, the solution presented shows how self-healing technology has significant potential in making complex systems more available and maintainable while ensuring continuous operation as well as enabling future autonomous engineering capabilities.
