Optimization of maintenance patrols planning

2021 29th Mediterranean Conference on Control and Automation (MED), 2021
Many industrial systems fail every year simply because a risk has been poorly assessed, ignored, or worse, unidentified. The prevention of the risks in several industrial domains is performed by using preventive maintenance to ensure safety and availability. For this purpose, we propose this contribution to investigate the integration of the Preventive

Optimal maintenance period and maintenance sequence planning under imperfect maintenance

Quality and Reliability Engineering International, 2022
AbstractMaintenance 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.

Optimizing test to reduce maintenance

21st IEEE International Conference on Software Maintenance (ICSM'05), 2005
A 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.

Optimal Contract for Machine Repair and Maintenance

Operations Research, 2021
Maintenance 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 ...

Optimal Maintenance Policy with Imperfect Preventive Maintenance

IEEE Transactions on Reliability, 1981
This 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.

Expert judgment in maintenance optimization

IEEE Transactions on Reliability, 1992
This 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
