On optimal maintenance of a series system
Microelectronics Reliability, 1983Maintenance of an n-unit series system with general distributions for failure-time and repair times has been discussed. The system has been identified by up and down states. It is assumed that there are a finite number of alternatives to a decision maker in each state.

Optimization of Dynamic Preventive Maintenance for Multicomponent Systems
2018 IEEE International Conference on Internet of Things (iThings) and IEEE Green Computing and Communications (GreenCom) and IEEE Cyber, Physical and Social Computing (CPSCom) and IEEE Smart Data (SmartData), 2018In safety-critical Cyber Physical Systems (CPS), effective maintenance is of utmost importance for the operation of equipment. Periodic maintenance can prevent or delay the occurrence of fault to a certain extent, but it inevitably leads to either “over-maintenance” or “non-timely maintenance”, which results in a waste of resources or safety risks in ...

Optimal Maintenance Design for a Simple Reparable System
2019 IEEE 58th Conference on Decision and Control (CDC), 2019This paper discusses an optimal corrective maintenance design for a simple reparable system. The primary interest is to optimize the availability of the system, which is defined as the probability that the system is operating properly when it is requested for use.

Maintenance resources optimization applied to a manufacturing system
Reliability Engineering & System Safety, 2006This paper presents an availability optimization of an engineering system assembled in a series configuration, with redundancy of units and corrective maintenance resources as optimization parameters. The aim is to reach maximum availability, considering as constraints installation and corrective maintenance costs, weight and volume.

On the evolution of an intelligent maintenance optimization system
Journal of the Operational Research Society, 2004Summary: In this paper the author reviews the development of an intelligent maintenance optimization system over the past 16 years. The paper starts with discussion of the initial motivation behind developing the system and the designs of the early versions of a computer program to access maintenance history data and provide an analysis.

Optimal Maintenance Policies for a System With Multiechelon Risks
IEEE Transactions on Systems, Man, and Cybernetics - Part A: Systems and Humans, 2008Aged fossil-fired power plants are on the great increase in Japan, and the importance of preventive maintenance (PM) increases for their steady operations. A plant consists of a wide variety of mechanical and electrical components. Various kinds of severe failures inherent in these components and their occurrence probabilities are different.

Optimizing preventive maintenance: a deteriorating system with buffers
Industrial Management & Data Systems, 2016Purpose Making decisions on preventive maintenance (PM) policy and buffer sizing, as is often studied, may not result in overall optimization. The purpose of this paper is to propose a joint model that integrates PM and buffer sizing with consideration of quality loss for a degenerating system, which aims to minimize the average operation cost for a ...

Optimal Structures and Maintenance Policies for PABX Power Systems
Operations Research, 1979A power system for a private automatic branch exchange (PABX) consists of n independent and identical rectifiers hooked up in parallel. The lifetime of each component is an exponential random variable with a known mean (MTBF). The system fails when the number of operating rectifiers is less than m(m ≤ n).

Maintenance Optimization for Asset Systems with Dependent Performance Degradation
IEEE Transactions on Reliability, 2013This paper presents a model for optimizing maintenance plans for an industrial system consisting of a number of assets with degradation and performance interaction between them. In particular, we consider an asset system with M identical non-critical machines feeding their output to a critical machine.
