Abstract

Reliability is defined as the length of time a component works without failing. The reliability function shows an estimate for the probable amount of time a component should work without experiencing failure. Fuzzy set theory is rather useful for evaluating ambiguity and vagueness that exists within reliability parameters. Fuzzy reliability can model more appropriately a components lifetime if the inputs on the system are fuzzy numbers. Also fuzzy parameters of function can be estimated as fuzzy numbers in a reliability analysis. In this study, the fuzzy lifetime of a component in a refrigerator with censored data is estimated via a fuzzy reliability function for modeling the uncertainty of the process.
