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 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.

Optimizing Routine Maintenance Team Routes
Proceedings of the 17th International Conference on Enterprise Information Systems, 2015Simulated annealing is a metaheuristic approach for the solution of optimization problems inspired to the controlled cooling of a material from a high temperature to a state in which internal defects of the crystals are minimized. In this paper, we apply a simulated annealing approach to the scheduling of geographically distributed routine maintenance ...

Expert judgment in maintenance optimization
IEEE Transactions on Reliability, 1992This paper proposes a comprehensive method for the use of expert opinion for obtaining lifetime distributions required for maintenance optimization. The method includes procedures for the elicitation of discretized lifetime distributions from several experts, the combination of the elicited expert opinion into a consensus distribution, and the updating

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.
