Reliability Analysis of Paper Plant using Boolean Function with Fuzzy Logic Technique

Abstract

Assessment of reliability analysis of paper plant with fuzzy logic technique has carried out in this paper. Fuzzy Weibull distribution and lifetime of a component is also determined. The paper plant is a complex system under consideration which consists of various subsystems such as chipping, feeding, pulp preparation, washing, screening, bleaching and paper production etc. The mathematical model has developed based on Boolean function technique. Reliability of paper plant is obtained in three different cases. Reliability of each component is discussed as when all failures follow fuzzy Weibull distribution and when all repair follow exponential distribution and mean time to failure is also determined. Finally, a numerical analysis is presented to illustrate the characteristics of fuzzy reliability and their -cuts.
