| Abstract: | In this paper, based on the repaired as old model, under the same storage condition and on the conditionthat there are at least Nsystems available for use with probability P0 during the designed storage period 0,T0], the spare parts number Mfor Nidentical systems is derived.Based on this model, for the Weibull distribution, utilizing the pivotal quantity and Fiducial distribution, the confidence interval of the spare parts number M isconstructed ;then based on the complete samples in life testing, utilizing the Fiducial method, the reliability andthe availability of this model' s repairable system are derived.Furthermore the computation method of the confidenceinterval of the spare parts number M is obtained. |
