the reliability analysis of the medical equipments can help to increase the availability and the efficiency of the systems. In this manuscript we present a simple method of decomposition that could be easily applied on the complex medical systems. Using this method we can easily calculate the effect of the subsystems or components on the reliability of the overall system. Furthermore, to invest...

Equipment logistics, maintenance, and repair are important aspects of construction equipment management. A well-managed equipment fleet helps reduce downtime, as well as total maintenance and repair costs. With quickly growing fleets of equipment, large contractors tend to divert the maintenance and repair of equipment from equipment managers to project managers. As a result, the equipment mana...

We develop and empirically implement a model of optimal replacement of rental equipment and apply the model to derive detailed optimal replacement strategies for five different types of rental machinery: 1) excavators, 2) high reach forklifts, 3) skid steers, 4) scissor lifts, and 5) telescopic booms. Using data on actual replacements, revenues, maintenance costs, new machine prices and resale ...

This paper presents a predictive study applied to a manufacturing equipment in order to predict malfunctions, and consequently enabling predictive maintenance practices. ARIMA forecasting methods are successfully compared with neural networks models, both used over data obtained from a monitoring system that continuously keeps track of the relevant equipment parameters. The results show that bo...

neers (ASME), which is the international design standard for pressure equipment. Along with design and production, plant maintenance technology is also important. Maintenance technology is formed on the three pillars of inspection, evaluation, and repair and replacement.3) Inspection is nondestructive inspection technology for detecting defects arising while the equipment is in service. Evaluat...

conclusion radiology equipment in tehran university of medical sciences have potential capacity, but they need repair, and better maintenance and management and application of standards for the imaging system needs organized supervisory mechanisms. materials and methods the study was performed in 16 hospitals, 4 faculties and three healthcare centers of tehran university of medical sciences. we...
