Every industry is dependent on some type of asset that keeps the business in business be it a computer, a CNC, or a megawatt transformer. In a large enterprise, reducing costs related to asset maintenance, repair, and ultimate replacement is at the top of management concerns. Downtime in manufacturing ultimately results not only in high repair costs, but in customer dissatisfaction and lower po...

David Ribes What are the utilities, values, dangers and proclivities in the use of the analytical terms “maintenance and repair"? In this article I focus on activities within sociotechnical systems that are sustained by relatively few technologies, but a great deal of social or emotional work. I do so to explore two analytical uses of maintenance and repair, and then to point out some of the da...

Maintenance activities are crucial for all manufacturing industries. To ensure availability and lifetime of production equipment, operations management logistics support maintenance need to evolve year after year. Besides, Centralised Workshops one the most interesting approaches reduce cost time required repair faulty equipment. Generally known in research community as ‘repair shops’, they aim...

In problems of maintenance optimization, it is convenient to assume that repairs are equivalent to replacements and that systems or objects are therefore brought back into an as-good-as-new state after each repair. Standard results in renewal theory may then be applied for determining optimal maintenance policies. In practice, there are many situations in which this assumption can not be made. ...

structural health monitoring of cracked structures is one of beloved subject of researchers recently. consider of crack behavior in the water and energy pipeline is important because of environmental problems. in this paper consider of crack parameters in the underwater pipe subjected to mechanical transient load is investigated. for this purpose, three- dimensional parametric model of cracked ...

ON OPTIMAL POLICIES FOR MULTI·REPAIR·TYPE MARKOV MAINTENANCE MODELS Yukio Hatoyama Tokyo Institute of Technology (Received April 6, 1978) This paper treats an extension of an optimal machine maintenance model with Markovian deterioration introduced by Derman. The system consists of an operating machine whose deterioration is Markovian, a finite number of identical spare machines, and several ty...
