Condition monitoring as part of an effective condition based maintenance has long been accepted in the academic and industrial world, 25 COMADEM conferences are proof of that. Various methods, algorithms, and tools have been developed to monitor the condition, detect faults, or predict the remaining useful life. Furthermore, there are methods available supporting the engineer to choose the appr...

Proactive maintenance is a solution to increase the availability of the production equipment in the process industry. It involves online condition monitoring of field devices and reliably diagnosing the reason behind any abnormal behaviour, thus helping to rationalise maintenance operations. Making the information of different industrial sites available for analysis, significant improvements co...

This paper considers a condition-based maintenance model for continuously degrading systems under continuous monitoring. After maintenance, the states of the system are randomly distributed with residual damage. We investigate a realistic maintenance policy, referred to as condition-based availability limit policy, which achieves the maximum availability level of such a system. The optimum main...

in this paper, we focus on a continuously deteriorating critical equipment which its failure cannot be measured by cost criterion. for these types of systems like military systems, nuclear systems, etc it is extremely important to avoid failure during the actual operation of the system. in this paper we propose an approach which constrains failure probability to a pre-specified value. this valu...

this paper studies a maintenance policy for a system composed of two components, which are subject to continuous deterioration and consequently stochastic failure. the failure of each component results in the failure of the system. the components are inspected periodically and their deterioration degrees are monitored. the components can be maintained using different maintenance actions (repair...

Unscheduled maintenance is a large cost driver for airlines, but condition monitoring and prognosis can reduce the number of unscheduled maintenance actions. The paper shows condition monitoring can be introduced into most system by adopting a data-driven approach and using existing data sources. The goal is to forecast the remaining useful life (RUL) of a system based on various sensor inputs....

In order to reduce operating costs and increase the operational stability, aviation industry is continuously introducing digital technologies automate state detection of their assets derive maintenance decisions. Thus, many efforts research activities have focused on an early fault prediction system failures. Since has mainly been limited calculation remaining useful lifetimes (RUL) neglected i...

Cellulosic paper and oil insulation in a transformer degrade at higher operating temperatures. Degradation is accelerated in the presence of oxygen and moisture. Power transformers being expensive items need to be carefully monitored throughout its operation. Well established time-based maintenance and conservative replacement planning is not feasible in a current market driven electricity indu...
