a few years after the implementation of computerize maintenance management systems (cmms), showing the analysis results of the collected data in these systems is necessary and important for continuing the usage of these systems. equipment downtime and cost data can identify patterns of equipment faults and equipment costs. it can also show deficiencies in the implementation of maintenance syste...

background: nowadays medical equipment plays an important role in the treatment and in the medical education. using outdated preventive maintenance (pm) system may cause problems in the cutting edge medical equipment, nervous system disease’s equipment (in diagnosis and treatment) which are crucial for every medical center. based on above facts we focused on nervous system treat units’ equipmen...

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...

In this paper, a new method for modelling and estimation of reliability parameters of power transformer components in distribution and transmission voltage levels for preventive-corrective maintenance schedule of transformers is proposed. In this method, with optimal estimation of Weibull distribution parameters using least squares method and input data uncertainty reduction, failure rate and p...

introduction: nowadays, medical equipment is essential to provide health care services in hospitals. since 20% of the hospitals costs are devoted to providing such equipment, an appropriate management is required to maintain it. in this study it is intended to investigate the maintenance management of medical equipment in hospitals. methods and materials: it is a cross-sectional study. the popu...

In case of leasing, the user rents equipment for a predetermined time. During this period, all maintenance actions are performed by the lessor. In this research paper, the aim consists to determine an optimal maintenance policy for ensuring a minimum reliability, required by the customer. Two strategies are proposed: the first consists to perform preventive actions whenever the system reliabili...

This study aims to select optimal maintenance strategy for components of an electric motor of the National Iranian Oil Refining and Distribution Company. In this regard, a method based on revised multi choice goal programming and analytic hierarchy process (AHP) is presented. Since improving the equipment reliability is an important issue, reliability centered maintenance (RCM) strategies are i...
