This paper deals with the flexible job shop scheduling problem with the preventive maintenance constraints where the objectives are to minimize the overall completion time (makespan), the total workload of machines and the workload of the most loaded machine. A fast heuristic algorithm based on a constructive procedure is developed to solve the problem in very short time. The algorithm is teste...

This paper deals with the problem of scheduling imperfect preventive maintenance (PM) of some equipment. It uses a model due to Kijima in which each application of PM reduces the equipment's e ective age (but without making it as good as new). The approach presented here involves minimizing a performance function which allows for the costs of minimal repair and eventual system replacement as we...

The complexity of power systems is increasing as new generating units are added to in order supply the growing economies. This has resulted further research into generator maintenance scheduling (GMS) problem which seeks ensure optimal preventive that effective and reliable. focused on developing a schedule using tri-objective model. GMS model solved two solution methodologies. first an exact m...

Preventive maintenance is the essential part of many maintenance plans. From the production point of view, the flexibility of the maintenance intervals enhances the manufacturing efficiency. On the contrary, the maintenance departments tend to know the timing of the long term maintenance plans as certain as possible. In a single-machine production environment, this paper proposes a simulation–o...

This paper describes the results of a pilot project where the Pacific Gas and Electric (PG&E) Gas Distribution department has applied workflow technology to improve certain maintenancerelated business processes. The pilot is testing the developed applications to manage district regulator station maintenance at one of the local offices. “Workflow is the IT supported simplification and automation...
