摘要
通过分析输入域软件可靠性模型和时间域软件可靠性模型的特点,建立一种基于输入域的非参数软件可靠性评估模型,从而克服一般输入域模型评估精度较差、无法预测的缺点.同时提出了基于非参数统计的方法来估计缺陷数和软件失效概率,从而为利用普通软件测试所获得测试数据进行软件可靠性评估提供了一种解决途径,实例验证表明了该评估模型可以较好地对软件可靠性进行评估,给出缺陷数和软件可靠性的合理估计,其估计精度不低于较好的时间域模型.
The concept and characteristics of software reliability models are introduced and analyzed. A method is presented for soft- ware reliability estimation that is input-domain based. It was developed to overcome some of the difficulties in using existing reliabili- ty models in critical applications. The software reliability model based on input-domain has certain advantages over ordinary software reliability models verified through the simulation experiment.
