Fault management

Fault management

Fault management refers to the process of detecting, isolating, and correcting faults or problems in a technological system. It involves a set of activities that are required to maintain network service levels, including pinpointing problems and performance degradation quickly, initiating controlling functions such as diagnosis, repair, testing, recovery, and backup, and ensuring the system is functioning optimally. Effective fault management is crucial due to the inherent fault-sensitive nature of technological systems.From: Fundamentals of EMS, NMS and OSS/BSS [2019], Management of International Networks [1999], Set theoretic approach to fault-tolerant control of linear parameter-varying systems with sensor reintegration [2019]

Once problems are detected, fault management is used to mitigate the impact of the problems and to manage the network repair process. The main tasks that need to be performed by a fault management system are fault tracking, failure diagnosis, and fault workaround.

Due to the inherent fault-sensitive nature of technological systems, effective fault management is crucial. Active fault-tolerant control (FTC) schemes regularly combine a fault detection and isolation (FDI) module (see e.g. Ding, 2008; Isermann, 2006) with controller reconfiguration (CR) (see e.g. Rauch, 1995; Steffen, 2005), to maintain closed-loop stability and system performance in the presence of various fault situations (see e.g. Blanke, Kinnaert, Lunze, & Staroswiecki, 2006; Ding, 2008; Isermann, 2006).

With the widespread use of such applications, the reliability of the whole system is challenged by the failure or faults of the elements. The elements failure and fault cause unwanted reactions, reduced efficiency, and low performance, or even system-wide failure. Due to the importance of continuous operation in many systems, such as electric vehicles, aircraft, as well as various industrial processes, the use of fault management methods is inevitable [3].
