The research on the method of fuzzy information processing

Abstract

In Reliability analysis, in addition to stochastic uncertain information, fuzzy uncertain information also exists. Therefore, the traditional reliability put forward a comprehensive method for reliability calculation of random uncertainty information and fuzzy uncertainty information. It obtained reliability distribution curve which is based on stress-strength interference model, also obtained reliability calculation model which could handle both the probability density function and the membership function. This paper explored the inner relation between this model and the classical reliability model. The result shows that: This model is used for processing stochastic uncertain information and fuzzy uncertain information in the case of coexistence of randomness and fuzziness. The result has high accuracy, and can dynamically reflect the calculation mechanism of reliability.
