摘要
Abstract
The existing reliability qualification test schemes need large workload with a specified risk level,but for the large complex equipment,abundant tests can not be carried out subj ect to limited outlay and test condition.To solve this problem,taking the system failure rate as a target,a new method is presented to make full use of the subsystem test data.Firstly,the subsystem test data is used to calculate the confi-dence bound of system failure rate.Then,the two-percentile method is applied to determine the prior distri-bution of system failure rate.Finally,a new reliability demonstration test scheme is defined according to the Bayesian maximum posterior risk rule.Compared with the classical reliability test scheme,the new scheme can obviously save test time and reduce the test workload.关键词
