| Abstract: | In safety-critical system,not only the software reliability often needs too much time in statistical test,but also critical operations often test not enough and cost very high.This paper describes the method of software reliability accelerated test based on Markov link usage model,which uses the method of stratified sampling and importance sampling.It partially resolves the above problems provided that the unbiased estimation of software reliability is derived from the statistical test results which amelior... |
