摘要
采用部件维修后随机状态模型与通用生成函数结合的方法,考虑部件维修后的多状态属性,将部件状态分为三类:更换件、不完全维修件、最小维修件,建立部件多状态可靠性评估模型,运用通用生成函数评估系统整体的可靠性,克服了传统方法单一评估不完全维修系统或退化系统可靠性时的片面性,以发动机引气系统的可靠性评估证实了方法的实用性。
The parts make repair random state model combined with general generating function method,considering parts after repair of state property,state of parts can be divided into three categories: the newreplacement parts,incomplete repair parts,minimum maintenance parts,establish the reliability ? model,using the universal generating function to calculate the probability distribution of the system,It overcomes the respectively that traditional method in system reliability assessment of incomplete maintenance or degradation system. It confirmed that the method is practical by the engine bleed air system reliability assessment.
