We develop a delay time model for a one component system with postponed replacement to
analyze situations in which maintenance might not be executed immediately upon discovery …

Maintenance optimization is the problem of determining cost-optimal maintenance decisions
for a system or structure to ensure safe and economic operation. An important concept in …

There are analysed and summarized the results of preventive maintenance, one of the most
commonly used maintenance strategy. The reviewed literature is classified into two main …

In this paper we develop statistical inference approaches for three age replacement policies;
classical age replacement, opportunity-based age replacement first and opportunity-based …

This paper focuses on the age replacement problems under the assumption that the arrival
of opportunities follows a stochastic point process. The opportunity is a chance to make the …

In this paper, we extend the existing opportunity-based age replacement policies by taking
account of dependency between the failure time and the arrival time of a replacement …

Abstract In operating Indonesian Navy Vessels (KRI), users often find some indicators
leading to the prediction that the system experiences a decline in performance or a …

In this paper we consider the optimal (T, S)-policies in a discrete-time opportunity-based age
replacement (DOAR), where S is a restricted duration of opportunities and T (≥ S+ 1) is a …

Age replacement is a well-established theoretical model for guidance on preventive
replacement of technical units, with the intention to replace units before failure, in a manner …

Au cours de ces dernières décennies, les systèmes technologiques ont beaucoup évolué.
Dans le même temps, leurs installations sont de plus en plus distribuées sur plusieurs sites …
