In the literature, preventive maintenance (PM) tasks are treated as one category of work such that they were interchangeable in scheduling. It is not practical in the real production system as different categories of maintenance tasks should be independent. Thus, this work modeled a new Production-Maintenance Scheduling (PMS) problem that considered different categories of maintenance with diff...

preventive maintenance scheduling of generating units is addressed as a long-term scheduling in power system studies aiming to increase the reliability incorporating cost reduction. it consists of knowing which generating units should be shut down for regular safety inspection. in this paper, a new formulation of preventive maintenance scheduling associated with cost reduction index (cri) is pr...

Preventive maintenance (PM) in the production industry is one of most essential measures to eliminate accidental machinery failures by replacing/repairing worn out machines or parts. The decision when and where perform preventive non-trivial due complex stochastic nature PM implemented. This article deals with theoretical practical implementation based on a unique modification total productive ...

The change of market and the explosion of product variety have led to increased automation and the need for complex equipment. Therefore, the reliability and the maintainability of the equipment play an important role in controlling both the quantity and quality of the products. In order to ensure specified availability and reliability of production process, preventive maintenance (PM) should b...

An age replacement maintenance policy is considered here, in which a system is restored whenever it fails, or ages without failure up to a preventive maintenance epoch (whichever comes first). The duration of the restoration activity is random, and depends on whether it was precipitated by a failure or by a preventive maintenance action. The case where the preventive maintenance epoch is determ...

In this paper, we investigate two dimensional leased contracts for a dump truck operated in a mining industry. To keep the truck in a good operational condition, an imperfect preventive maintenance (PM) policy is applied. When the truck fails then corrective maintenance (CM) is done. PM and/or CM can be leased to an external agent or a lessor for an economic reason. The situation under study is...

The buffer allocation problem is an NP-hard combinatorial optimization problem, and it is an important design problem in manufacturing systems. The research proposed in this paper concerns a product line consisting of n unreliable machines with n − 1 buffers and a preventive maintenance policy. The focus of the research is to obtain a better trade-off between the buffer level ...

Computerized maintenance management systems (CMMS) are required to manage and control asset, plant, and equipment maintenance in today’s hospitals. A CMMS is much more than just a way to schedule preventive maintenance (PM). By using a CMMS, you can create equipment logs to record events associated with a piece of equipment; create work orders automatically according to a schedule or manually f...

A bstract The inventory control of repair parts has recently become an important subject in rationalizing logistics department. Information network systems for repair parts are being constructed. The purpose of this study is to propose a fixed interval ordering policy for repair parts of single item and clarify its effects. The proposed policy specifically takes into account the characteristic ...
