Abstract: High-quality maintenance is crucial to extend the life cycle of systems. Deficient procedures due to components with hidden flaws, incorrect refurbishing, or undertrained operators can seriously compromise that systems keep on working. This work analyzes the adverse effect using two policies based on mixtures of distributions to model either hidden defects due to undersized components or poor repairs leading to a diminished reliability. The first approach uses a defective distribution to describe the presence of a subpopulation free of defects. The second one deals with mixtures of nonhomogeneous Poisson processes to model repairs that restore the functionality of the system but with a worse-than-old condition. The results show that low-quality maintenance leads to a reduction of the optimal usage time, which is a serious detriment to sustainability. The most recent literature on this subject is also reviewed.
