基于Petri网和模糊λ-τ方法的冰箱生产系统可靠性分析

he present paper has put forward a kind of reliability analysis method in which involves qualitative modeling using PN and quantitative analysis using Lambda-Tau method of solution with the basic events. In view of reliability parameters of refrigerator production system: reliability, availability, MTBF (mean time between failures), ENOF(expected number of failures), failure rate and repair time, a structured framework has been developed. This method has important reference value for the plant personnel for analyzing the systems' behavior and to improve their performance by adopting suitable maintenance strategies.
