Reliability Engineering & System Safety, 2020
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 which reveal the real states of the system with non-constant ...

Optimal maintenance policies for coherent systems with multi-type components
Reliability Engineering & System Safety, 2020We propose two new optimal maintenance strategies for preservation of a complex n-component coherent system. The criteria that will be optimized are some given imposed cost functions formulated based on the costs of the repairs of components (system) to ...

Optimal maintenance period and maintenance sequence planning under imperfect maintenance
Quality and Reliability Engineering International, 2022AbstractMaintenance is essential for today's equipment or systems and maintenance costs account for a significant portion of the overall expenditure of devices. Maintenance period optimization and maintenance sequence planning are primary aspects of maintainability.

Optimal Contract for Machine Repair and Maintenance
Operations Research, 2021Maintenance outsourcing is quite common in industries that rely on complex and critical equipment. Instead of investing in the maintenance facilities, firms outsource maintenance activities to specialized companies. However, it may be hard for firms (i.e., principal) to observe whether maintenance companies (i.e., agent) put sufficient resources into ...

Optimizing test to reduce maintenance
21st IEEE International Conference on Software Maintenance (ICSM'05), 2005A software package evolves in time through various maintenance release steps whose effectiveness depends mainly on the number of faults left in the modules. Software testing is one of the most demanding and crucial phases to discover and reduce faults. In real environment, time available to test a software release is a given finite quantity.

Availability and optimal maintenance policy for systems degrading in dynamic environments
European Journal of Operational Research, 2019In both engineering practice and theory, system degradation is often modeled by a stochastic process. When the degradation behavior is significantly affected by environments, a single stochastic process is not suitable to describe the system degrading in

Optimal Maintenance Policy with Imperfect Preventive Maintenance
IEEE Transactions on Reliability, 1981This paper considers a maintenance policy with imperfect preventive maintenance (pm). After pm, the failure characteristic of the system is different (worse) from that of correctively maintained system (viz. after a failure). Optimal policy which minimizes the mean cost-rate is discussed.

Maintenance optimization models and criteria
International Journal of System Assurance Engineering and Management, 2010Due to widespread automation and the high capital tied up in production equipment, the importance of maintenance is ever increasing. This makes maintenance an investment opportunity to be optimized, not a cost to be minimized. Academics have recognized this and many maintenance optimization models have been published over the years.
