In order to identify bottlenecks in the equipment operation and accumulate data for development of organizational technical measures reduce unplanned downtime, JSC “Vyksa Metallurgical Plant” keeps records downtime main technological equipment. All is recorded by production personnel automated analysis system workshop. Reliability specialists workshops have classified all units into criticality...

Virtual machine checkpoints provide a clean encapsulation of the full state of an executing system. Due to the large nature of state involved, the process of VM checkpoints can be slow and costly. We describe the implementation of a a fast and lightweight mechanism of VM checkpointing for the Xen virtualization machine monitor that utilizes copy-on-write techniques to reduce the VM’s downtime a...

Semiconductor wafer fabrication is perhaps one of the most complex manufacturing processes found today. In this paper, we construct a simulation model of part of a wafer fab using ProModel software and analyze the effect of different input variables on selected parameters, such as cycle time, WIP level and equipment utilization rates. These input variables include arrival distribution, batch si...

Hydride gases, such as phosphine and arsine, are important contaminants in process chemicals used in both the petrochemical and semiconductor industries. For example, the presence of phosphine, arsine, hydrogen sulfide and carbonyl sulfide in polymer grade ethylene or propylene can have a deleterious effect on catalysts used in the production of polypropylene plastics. Accurate data on the conc...

A stable network is very important to both providers and their customers, as it increases reliability, improves security helps customers companies save costs. When outages occur, they result in significant downtime financial losses for organizations users. Traditional methods of detecting troubleshooting failures are often reactive time-consuming, whereby administrators rely on traditional such...
