My research focuses on two fields related to system reliability. The first one is devoted to the ageing characteristics, i.e. reliability metrics. The second is centered on maintenance model building in order to prevent systems from failing. These procedures contibute to system availability whenever its use is required, while extending its service life. Maintenance can include inspecting the system to detect failures that remain hidden otherwise, and the time interval between inspections is a crucial decision variable harboring implications in practical applications. My investigation also concerns low-quality maintenance. This is supported in practice by several factors, such as the use of defective materials, spares with hidden defects, or imperfect refurbishing. The result, in these cases, is that the reliability after maintenance is lower than expected.
