Improvement of Gas Turbine Availability Using Reliability Modeling Based on Fuzzy System

The development of the reliability approaches mainly aims at finding the probability that the studied system or a part of it will perform the required function without interruption or failure under the actual stated conditions of defects for a determined period. In this work, the analysis of the effects and consequences resulting from the failures that can affect the industrial system itself and its environment is proposed, where an application on gas turbine system is presented. The main objective is to identify the impact of the gas turbine rotor vibration on the turbine itself and on the operator based on reliability modeling. Indeed, this approach will allow to discover accurately the causes of this kind of vibration. In this paper, a fuzzy modeling method to optimize reliability and availability of the gas turbine is proposed, with the main aim to improve the system exploitation and monitoring.
