We consider the task of devising an effective metaheuristic for a variant of the preventive maintenance scheduling problem (PMSP) — the (power) generator maintenance scheduling problem (GMSP). Recent research on metaheuristics for this problem has made progress on it, but the potential economic benefits of effective methods is significant in this area, and warrants further focused work. We prop...

We develop a preventive maintenance (PM) model for a unit operated under stressful environment. The PM model in this paper consists of a failure rate model and two cost models to determine the optimal PM scheduling which minimizes a cost rate. The assumption for the proposed model is that stressful environment accelerates the failure of the unit and periodic maintenances reduce stress from outs...

Quality assurance in nuclear medicine refers collectively to all aspects of a nuclear medicine service. It would include patient scheduling, radiopharmaceutical preparation and dispensing, radiation protection of patients, staff and general public, preventive maintenance and the care of instruments, methodology, data interpretation and records keeping, and many other small things which contribu...

CONTEXT The annual physical examination is a staple of North American medicine. Medicare does not pay for such visits, and the United States Preventive Services Task Force designates these visits as preventive services. OBJECTIVE To understand the expectations of receptionists, patients, and physicians as well as their reasons for scheduling a health maintenance visit and to clarify the expec...

In this paper, a challenging power system problem of effectively scheduling generating units for maintenance is presented and solved. The problem of generator maintenance scheduling (GMS) is solved in order to generate optimal preventive maintenance schedules of generators that guarantee improved economic benefits and reliable operation of a power system, subject to satisfying system load deman...

In this article we give an overview of the relation between planning of maintenance and production. On the one hand we consider production planning and scheduling models where failures and maintenance aspects are taken into account. Next we discuss the planning of maintenance activities, where we consider both preventive as well as corrective maintenance. Thirdly, we consider the planning of ma...

This paper considers the problem of scheduling hybrid flowshops with machine availability constraints (MAC) to minimize makespan. The paper deals with a specific case of MAC caused by preventive maintenance (PM) operations. Contrary to previous papers considering fixed or/and conservative policies, we explore a case in which PM activities might be postponed or expedited while necessary. Regardi...
