In order to perform Preventive Maintenance (PM), two approaches have evolved in the literature. The traditional approach is based on the use of statistical and reliability analysis of equipment failure. Under statistical-reliability (S-R)-based PM, the objective of achieving the minimum total cost is pursued by establishing fixed PM intervals, which are statistically optimal, at which to replac...
Induction machines are the backbones of many industrial processes due to its robustness and reliability. Condition monitoring of induction motors is the process of monitoring the behavior of motor before significant change which leads to developing fault. Online fault diagnostics of induction motor is important, and its real function is to attempt to recognize the development of faults at an ea...
Internet software is an emerging software paradigm. Traditional evaluation methods for software reliability are no longer applicable because of the open and dynamic characteristics of the Internet software. In order to evaluate its reliability accurately, there must be a dynamic and open reliability evaluation approach. This paper presents the collection approach of the reliability-related data...
Estimating the reliability of individual classifications is very important in several applications such as medical diagnosis. Recently, the transductive approach to reliability estimation has been proved to be very efficient when used with several machine learning classifiers, such as Naive Bayes and decision trees. However, the efficiency of the transductive approach for state-of-the art kerne...
Preventive maintenance scheduling of generating units is addressed as a long-term scheduling in power system studies aiming to increase the reliability incorporating cost reduction. It consists of knowing which generating units should be shut down for regular safety inspection. In this paper, a new formulation of preventive maintenance scheduling associated with cost reduction index (CRI) is pr...
In the article, approach of integrated statistical control and diagnostics radio-electronic equipment, which is based on analysis, integration measuring information arriving from thermal imager, magnetic field sensors, tension humidity air also equipment parameters, presented. The solution a problem monitoring changes in average level multi-parameter process. Here, Hotelling charts, processing ...
A condition based preventive and corrective maintenance policy is proposed for a continuously operating system. The condition of the system is assumed to deteriorate with time. The model incorporates both deterioration as well as random common cause failures. The deterioration stages are modeled as discrete state processes. The system is put to random inspection to know the condition. The mean ...
