一种基于可用度的装备贮存模型及其应用

考虑工程实际中对装备贮存可靠性指标的要求,在修如旧贮存模型的基础上,提出一种基于可用度的装备贮存模型,即对设备定期实施大修措施以保证该设备的可用度不低于临界水平α,并给出了对设备实施大修措施的固定时间间隔的计算方法,这样在该贮存模型中,设备可用度在整个贮存过程中始终不低于临界水平α,很好地满足了实际应用中的需求.在该模型下,针对贮存寿命服从威布尔分布的设备,利用Fiducial方法确定对设备实施大修措施的固定时间间隔,并给出了一个模拟算例.

One Kind of Modified Repaired as Old Storage Model and It's Application

According to the requirement of engineering, the availability of storage system should be always not less than an certain level α. Based on the repaired as old model, we add the repaired as new measure to the storage system on fixed time to ensure that the availability is always not less than α, then we derive the fixed time for the repaired as new measure. Finally we, apply this model to repairable Weibull distributed systems. and based on the complete samples in life testing, we use the Fiducial method to...
