Nowadays, an efficient and robust plan for maintenance activities can reduce the total cost
significantly in the equipment-driven industry. Maintenance activities are directly associated …

Maintenance is a challenging operational problem where the goal is to plan sufficient
preventive maintenance (PM) to avoid asset overhauls and failures. Existing work typically …

This paper presents a new variant of the selective maintenance problem (SMP) to jointly
optimize the maintenance planning and resource allocation problems for multiple missions …

During system operation, inspections are usually scheduled to detect the signals of defects.
Due to the human, measurement or environment errors, inspections are generally imperfect …

This paper studies a condition-based predictive maintenance policy in the presence of
imperfect repairs for deteriorating systems. The effect of imperfect repairs is assumed to be …

In this article, a novel maintenance model is proposed for single-unit systems with an
atypical degradation path, whose pattern is influenced by inspections. After each inspection …

Manufacturers usually want to predict the warranty cost for new products under affordable
maintenance policies. With insufficient reliability information, experimental degradation tests …

We consider the problem of optimally maintaining a periodically inspected system with multi-
level preventive maintenance whose effects are complex. At each inspection, the …

In the majority of the existing preventive optimization models only costs related to
maintenance actions are accounted for, while breakdown and operational costs are usually …

Upgrade operations are improvement actions that can be carried out on recovered end-of-
life systems to rejuvenate them and make them fit for subsequent lifecycles. These …
