In this research, computerized maintenance management will be investigated. The rise of maintenance cost forced the research community to look for more effective ways to schedule maintenance operations. Using computerized models to come up with optimal maintenance policy has led to better equipment utilization and lower costs. This research adopts ConditionBased Maintenance model where the main...

 In this paper a single server queuing production system is considered which is subject to gradual deterioration. The system is discussed under two different deteriorating conditions. A planning horizon is considered and server which is a D/M/1 queuing system is gradually deteriorates through time periods. A maintenance policy is taken into account whereby the server is restored to its initial ...

Increasing dependence of business on 24/7 IT systems sets requirements to support recovery from hardware, software and operational errors and reduce number and length of maintenance windows through online and automated or semi-automated system management activities. These requirements cannot be satisfied purely by technology let alone a single technological innovation on a single layer of a sys...

This is a proposal of the content of a licentiate thesis in Innovation and Design at Mälardalen University, Sweden. The contents of the licentiate thesis are concerning Condition Based Maintenance (CBM) in technical systems. The need to make more effective maintenance actions have been shown in various national and international scientific papers. It has also been shown that the traditional mai...

Condition-based maintenance (CBM) presently plays an important role in avoiding unexpected failures, improving machine reliability, and providing accurate maintenance records and activities for rotating machinery. Traditional wired sensors commonly used for gathering data are costly and of limited value in industry. Recently, together with the advancement of sensor technology and communication ...

We develop a framework for studying dynamical properties of hybrid systems based on considering the space of all possible trajectories of the system. In this way it is possible to treat both nondeterministic systems and systems for which the evolution does not depend continuously on the initial conditions. We show that the trajectory space is compact for the class of upper-semicontinuous hybrid...

For the safe, stable, and economic operation of thermal power units in new systems, condition-based maintenance mode storage strategy key equipment materials for generation enterprises were selected. According to linkage demand maintenance, a Weibull probability density function was used calculate spare parts demand, an intelligent optimization model with availability constraint established. Th...
