多台同步可靠性增长模型存在的问题

探讨多台可靠性增长模型的统计意义,指出多台同步纠正可靠性增长试验丢掉了本可得到的大量的试验信息,失去了统计试验意义,其 AMSAA-BISE模型不能成立,多台同步试验方法不可取

EXISTING PROBLEMS OF MULTIPLE-SYSTEM SYNCHRO-CORRECTION RELIABILITY GROWTH MODELS

The statistical results of the reliability growth test of multi systems have been investigated. The results show that some useful information would be lost if the synchronizing correction is used in the test, and because a multi sample statistical test will become a single sample test, whose failure probability obeys the combined distribution, the estimation results would not be correct. The synchronizing correction reliability growth test of multi systems is not better than the asynchronous one in providing estimation information, and it will spoil the statistical test. So, it is reasonable to use the asynchronous reliability growth test rather than the synchronous one.
