Online updating belief rule based system for pipeline leak detection under expert intervention

Bayesian reasoning approach based recursive algorithm for online updating belief rule based expert system of pipeline leak detection

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...

Inference and learning methodology of belief-rule-based expert system for pipeline leak detection

Belief rule based expert systems are an extension of traditional rule based systems and are capable of representing more complicated causal relationships using different types of information with uncertainties. This paper describes how the belief rule based expert systems can be trained and used for pipeline leak detection. Pipeline operations under different conditions are modelled by a belief...

A sequential learning algorithm for online constructing belief-rule-based systems

A belief rule base inference methodology using the evidential reasoning (RIMER) approach has been developed recently. A belief rule base (BRB), which can be treated as a more generalized expert system, extends traditional IF-THEN rules, but requires the assignment of some system parameters including rule weights, attribute weights, and belief degrees. These parameters need to be determined with...

Leak Detection in Gas Pipelines - a Knowledge Based Approach

Leak detection systems are a fundamental part of the management system associated with any long distance pipeline. Such systems are necessary to avoid or reduce environmental and economical losses in case a leak develops in the pipeline. There are several solutions, with different efficiency and cost-effectiveness, for this problem. One of the most appealing is the use of software based leak de...
