摘要
本文在对文[4]中软件可靠度的估计进行研究的基础上,提出了软件总体可靠性的一个新模型,对软件总体的可靠度进行了讨论,利用点估计方法,得到软件可靠度的点估计值,证明了软件总体失效率λ估计解的唯一性,并对缺陷数进行了估计,从而给出了新模型下软体总体可靠性的估计.
We give a new model of the software reliability based on the study of the paper [4]. We discuss the reliability of the population and give the value of the reliability of the software with the method of point estimation. We testify that the failure rate λ have the only root, and give the number of the defaults. We give the estimation of the new model of the reliability of the software population.
