Reliability evaluation based on a fuzzy expert system: Centrifugal pump application

Abstract

In the development process of modern industrial systems, predictive reliability becomes very important in the design and exploitation of industrial facilities. This paper proposes the development of a new approach to the assessment of predictive reliability, applied to a centrifugal pump based on a fuzzy expert system to improve its performance under actual operating conditions. The obtained results clearly demonstrate how the reproduction of the main dynamic characteristics of the examined pump, using the proposed fuzzy model enables better performance regarding reliability.
