This paper provides an overview of the historical evolution of reliability in the scientific area
of operations research. Historical views and future perspectives are specifically offered with …

Most of the systems are treated as repairable in automobile, nuclear and aviation industries,
and often subjected to imperfect maintenance. Reliability assessment of such systems is …

An appropriate maintenance policy is essential to reduce expenses and risks related to
equipment failures. A fundamental aspect to be considered when specifying such policies is …

There is an extensive literature on imperfect maintenance models. Among them, we have
proposed in Doyen and Gaudoin (2004)[13] the classes of ARA and ARI models. These …

Manufacturing machines usually work under piecewise constant operating condition
(PCOC) and are subject to imperfect preventive maintenance (PM). In this paper, an …

The paper proposes a new maintenance model for a repairable system. The system is
inspected at deterministic times. If a failure occurs between two successive inspections, a …

This paper presents a case study of technical and economic optimization of the periodicity of
predetermined preventive maintenance actions carried out on a repairable industrial system …

In the repairable systems literature one can find a great number of papers that propose
maintenance policies under the assumption of minimal repair after each failure (such a …

Imperfect repair (IR) modelling has attracted a lot of attention during the last decades. To
assess and predict repairable systems' reliability, analysts have to choose among a plethora …

Purpose While steady-state analysis is useful, it does not consider the inherent transient
characteristics of repairable systems' behavior, especially in systems that have relatively …
