Acquiring Knowledge for Linking Maintenance and Evaluation of Experience-based Information Systems
نویسندگان
چکیده
The value of most experience-based information systems tends to degrade with time. To keep the value of such a system, evaluation and maintenance is an essential. While evaluation monitors the "value" over time, maintenance has to preserve or improve this "value". Evaluation and maintenance should not simply happen ad-hoc but systematically and based on specific quality and maintenance knowledge, which is linked to base maintenance on evaluation. As a jump-start for evaluation and maintenance, the respective knowledge should be available right from the start of continuous operation. This paper describes how to acquire and develop such maintenance knowledge during system buildup to use and improve this knowledge during continuous operation for combined humanand computerbased maintenance. The described approach has been successfully applied in several projects. The method is illustrated with examples from two of these projects as case studies.

متن کاملAvailability analysis of mechanical systems with condition-based maintenance using semi-Markov and evaluation of optimal condition monitoring interval
Maintenance helps to extend equipment life by improving its condition and avoiding catastrophic failures. Appropriate model or mechanism is, thus, needed to quantify system availability vis-a-vis a given maintenance strategy, which will assist in decision-making for optimal utilization of maintenance resources. This paper deals with semi-Markov process (SMP) modeling for steady state availabili...
