摘要

In industrial plants, the reliability analysis and evaluation approaches are used mainly to avoid the failures and the damage of the equipment, where the main aim is to increase their life cycle. Within this framework, the present paper deals with the modeling of the reliability which is characterized by a rate failure function with a bath form shape, applied to a gas turbine system. In this paper, the mathematical tools based on modified Weibull distribution are integrated to determine the robust reliability models of the studied system. The proposed approach aims to ensure the operational availability of the studied system with a logistic function which allows to organize and to carry out series of precautions to avoid the unexpected failures. Finally, simulation results have been performed for the validation of the proposed approach in comparison to other standard reliability approaches.
