Abstract

In power production, gas turbines are commonly used components that generate high amount of energy depending on size and weight. They function as integral parts of helicopters, aircrafts, trains, ships, electrical generators, and tanks. Notably, many researchers are focusing on the design, operation, and maintenance of gas turbines. The focal point of this paper is a DEMATEL approach based on fuzzy sets, with the attempt to use these fuzzy sets explicitly. Using this approach, the cause-effect diagram of gas turbine failures expressed in the literature is generated and aimed to create a perspective for operators. The results of the study show that, "connecting shaft has been broken between turbine and gear box" selected the most important cause factor and "sufficient pressure fuel does not come for fuel pump" is selected the most important effect factor, according to the experts.
