Fault Diagnosis Based on Belief Rule Base With Considering Attribute Correlation

Online Fault Detection and Isolation Method Based on Belief Rule Base for Industrial Gas Turbines

Real time and accurate fault detection has attracted an increasing attention with a growing demand for higher operational efficiency and safety of industrial gas turbines as complex engineering systems. Current methods based on condition monitoring data have drawbacks in using both expert knowledge and quantitative information for detecting faults. On account of this reason, this paper proposes...

Integrating Belief Functions with Model-based Diagnosis for Fault Management

The simulation model of a device/system available from design implies the use of model-based approach in the manufacturing fault diagnosis. The model-based diagnosis uses knowledge of the structure and behaviour of a device and observations of the device’s behaviour to discover the causes of malfunctions. The major difficulty of model-based diagnosis is to eliminate hypotheses accounting for al...

A Fuzzy Rule Based System for Fault Diagnosis, Using Oil Analysis Results

    Condition Monitoring,   Oil Analysis, Wear Behavior,   Fuzzy Rule Based System   Maintenance , as a support function, plays an important role in manufacturing companies and operational organizations. In this paper, fuzzy rules used to interpret linguistic variables for determination of priorities. Using this approach, such verbal expressions, which cannot be explicitly analyzed or statistic...

Automated IT service fault diagnosis based on event correlation techniques

A model for real-time failure prognosis based on hidden Markov model and belief rule base

As one of most important aspects of condition-based maintenance (CBM), failure prognosis has attracted an increasing attention with the growing demand for higher operational efficiency and safety in industrial systems. Currently there are no effective methods which can predict a hidden failure of a system real-time when there exist influences from the changes of environmental factors and there ...
