ophthalmic equipment, including surgical instruments and diagnostic devices, can be compared to the maintenance of a motor vehicle, something many of us understand well. If you had a car, would you drive it until the fuel runs out or until a tyre punctures, and then abandon it to buy a new car? Of course not. However, many eye care units purchase (or receive as a donation) expensive and delicat...

Production planning and maintenance are two important problems in manufacturing systems. Despite the relationship exists between these two problems due to sudden failures and production capacity occupied by maintenance activities, each of these problems planned separately and as a result program and model efficiencies reduce in the real world. The aim of integrated production and maintena...

The research investigates the influence of an effective maintenance system on the efficient performance of any industrial system. The core concept of the research explains that the simultaneous focus on the spares inventory subsystem as well as on the preventive maintenance subsystem must be considered when developing a quality maintenance programme. Considering and developing such aspects sepa...

Navy has made a huge applying of preventive maintenance that has been recognized as the greatest source of costs. Scheduled overhaul is the most expensive. Revising preventive maintenance and selecting maintenance concepts according to a new algorithm should result into lowering those costs and at the same time maintaining function safety and system readiness. A reversible FMEA analysis coupled...

This paper presents a method to find the optimum maintenance policy for a component. Random failures and failures due to deterioration are considered. Using Markov processes, the state probabilities are calculated and the optimal value of the mean time to preventive maintenance is determined by maximizing the availability of single component with respect to mean time to minimal preventive maint...

Corrective maintenance (CM) is carried out to correct failures while preventive (PM) avert failure. They both play an important role in asset management. Accurately estimating the effectiveness of PM needed as it has impact on system health Given failure times and related data, possible estimate maintenance. This paper proposes CM models based different combinations type out, estimates paramete...

In the move towards world-class manufacturing, many firms are realizing a need for the use of proper maintenance of production facilities and systems. Industrial plants, machines and equipment are becoming technologically more advanced and at the same time more complex and difficult to control. Therefore, the importance of the maintenance function has been greater than before, due to its role i...

The economic and political realities of the 1990s forced managers to reverse long-standing organizational cultures in order to reduce costs and energy expenditures in their organisations. For instance, these can be achieved, with respect to maintenance, by replacing a reactive repair-focused attitude by a proactive reliability-focused culture. Thereby far less (i) human effort is expended and (...
