Fuzzy Availability Research Of Maintainable Systems Based On Structured Element Theory

Largely and complexly engineering system often is repairable system.Repairable system with two systems inherent attributes, can measured by the system availability.In view of the repairable system failure rate and repair rate is usually the fuzzy parameters, Put forward the fuzzy concept of availability.Due to the complexty of traditional fuzzy mathematics,theory of fuzzy structural units can convert traditional arithmetic of fuzzy number to fuzzy linear structure to generate fuzzy number operational,It is a good solution to the traditional fuzzy analysis method of complex defects.Using the theory of fuzzy structure element research:Series repairable system, establishing the model of fuzzy failure rate, fuzzy repair rate, fuzzy failure and repair rate and the fuzzy structural solution;Parallel repairable system, establishing the model of fuzzy failure rate, fuzzy repair rate,fuzzy failure and repair rate and and the fuzzy structural solution;Repairable maintainable k/n systems, establishing the fuzzy failure rate, repair rate, fuzzy failure rate model and the fuzzy structural solution.
