In data-driven prognostics and health management (PHM), most studies focus only on
prognostics performance but rarely consider maintenance decision problems. However …

Competing failures are extensively observed in complex industrial systems, which may
result in tremendous economic losses and safety hazards. In this article, we study a system …

Condition-based maintenance (CBM) is a key measure in preventing unexpected failures
caused by internal-based deterioration and external environmental shocks. This study …

This paper investigates an extended replacement policy for a two-unit system subject to
shocks and cumulative damage. As a shock occurs, the system suffers two types of effects …

This paper investigates the preventive replacement policies for an operating system that
works for projects at random times. The system is subject to shocks which arrive according to …

The number of aged plants and infrastructures has been greatly increasing in advanced
nations [1]. In order to conduct safe and economical maintenance strategies, modeling and …

Abstract Models are introduced and examined for the optimum scheduling of preventive
replacements. The “replace first” and “replace last” models are known from the literature if …

In the δ-shock model, a system fails if the interval time between two consecutive shocks is
less than a fixed threshold δ, which can be seen as the system recovery time from a shock …

This paper proposes age and periodic replacement last models with continuous, and
discrete policies. That is, an operating unit is replaced preventively at time T of operation as …

Abstract Machine reliability and product quality are usually investigated independently in
most traditional models. However, in the actual manufacturing process, machine reliability …
