Abstract. PT X is a manufacturing company in publishing, printing, security and general trade. The has several large machines to support the production process. also provides spare parts used for engine repair problem at high time take wait that cause downtime. activity of taking makes 60 minutes waiting takes 2.880 minutes. due storage does not separate old new parts, are arranged according ty...

Moving machinery is the backbone of socio-economic development. The use machines helps in increasing production everyday used items, and tools, that generate electricity mechanical energy, provides easy fast transportation help by saving human efforts, time. industry totally dependent on bearing it considered bread butter system. Bearing failure about 40% total failures induction motors which w...

Highly available software systems occasionally need to be updated while avoiding downtime. Dynamic software updates reduce downtime, but still require the system to reach a quiescent state in which a global update can be performed. This can be difficult for multi-threaded systems. We present a novel approach to dynamic updates using firstclass contexts, called Theseus. First-class contexts make...

In this paper, we study N-policy for a finite population Bernoulli feedback queueing model for machine repair problem with degraded failure. The running times of the machines between breakdowns have an exponential distribution. The repair times of the machines are independent and identically distributed random variables. If at any time a machine fails, it is sent to the repairman for repairing,...

Availability of business-critical application servers is an issue of paramount importance that has received special attention from the industry and academia. To improve the availability of application servers, we have conducted a study of virtualization technology and software rejuvenation that follows a proactive fault-tolerant approach to counter act the software aging problem. We present Mar...

This paper deals with the G/G/R machining system consisting of M operating machines as well as S cold standbys. The concepts of balking and reneging are incorporated which make our model more versatile to deal with real time systems. The broken-down machines are sent to repair facilities consisting of R permanent repairmen. The failure times and repair times are generally identical and independ...

The electronics and semiconductor industries rely heavily on failure and defect analysis to maximize productivity and minimize expensive downtime. As technology improves, manufactured devices get smaller and the processes used to make them become more intricate. Costly downtime associated with the presence of particulate and chemical contamination becomes more critical to a successful manufactu...

The problem of operational efficiency assessment medical equipment is becoming crucial, due to its increasing requirement in hospitals. It has been observed that a significant amount out service for several reasons such as lack training, maintenance and health technology management. unexpected failures, downtime associated with breakdown make ready, loss production poor costs are the major draw...
