System Availability Test Procedure with Minimum Operating Time

Abstract

In order to solve problem about how to test inherent availability of repairable system under minimum operating time and lognormal repair time, an inherent availability test procedure with fixed sample size is presented. The test procedure which is divided into alternate operating and repair process, should meet stated levels of producer’s risk and consumer’s risk. It is noticeable that minimal sample size and critical value calculation method research is considered as the key point of procedure design. At the end of this paper, course of a test procedure design and operation of inherent availability test and evaluation are described by example analysis.
