electric power industry have always try to provide reliable electricity to customers and at the same time decrease system costs. high voltage circuit-breakers are an essential part of the power network. this study has developed a maintenance and replacement scheduling model for high voltage circuit- breakers that minimize maintenance costs while maintaining the acceptable reliability. this mode...

Maintenance and, in particular, maintenance policy plays a major -*art in achieving systems operational effectiveness at minimkm cost. The traditional approach to maintenance planning involves selecting optimal policies from known maintenance strategies such as scheduled inspection, preventive maintenance, corrective maintenance, oncondition maintenance etc. Using a traditional approach one may...

Reliability centered maintenance (RCM) is a new strategic framework for evaluating system requirements in its operating conditions. Some industries employ predictive strategies addition to preventive (PM) strategies, which increase production costs. As the breakdown (BDM) technique used, cost increases. The RCM approach mixture of these that can be used optimize costs and ensure availability sy...

In this paper, we develop reliability and conditionbased maintenance models for a multi-component system of stents implanted in human arteries that is subject to both delayed and instantaneous failures. Considering the physics of failure and probability of failure, we develop a system-level reliability model and maintenance strategy by merging fracture mechanics and stochastic process approache...

deregulation policy has caused some changes in the concepts of power systems reliability assessment and enhancement. in this paper, generation reliability is considered, and a method for its assessment using intelligent systems is proposed. also, because of power market and generators’ forced outages stochastic behavior, monte carlo simulation is used for reliability evaluation. generation reli...

The canonical decomposition of sequence describing the change of cardiograms is put in the basis of the method for a computer system of disease diagnostics. Obtained criterion of the solution of the problem of electrocardiograms classification is considerably simpler than the known criterion of making decision on the basis of the criterion of the maximum of density of distribution. The transiti...

Technical systems are in general not guaranteed to work correctly. They are more or less reliable. One main problem for technical systems is the computation of the relisystem description ability of a system. A second main problem is the problem of diagnostic. In fact, these problems are in some sense dual to each other. In this paper, we will use the concept of probabilistic argumentation syste...
