摘要
本文讨论进行计算机软件可靠性模型评价工作的必要性及其实现方法,提出了软件可靠性模型评价的四条标准,并由此引入了一种进行软件可靠性模型评价的方法。在本文的(Ⅱ)中,我们将使用本方法和两组具体的软件失效数据,具体地评价两种软件可靠性增长模型:S-型模型和W-NHPP模型的性能,并讨论方法使用中的一些问题。
In spite of much research effort, there is no universally applicable software reliability model which can be trusted to give accurate predictions of reliability in all circumstances. A set of criteria is proposed and a approach is set for comparison of software reliability models in this paper. The intention is to provide a logically organized basis for determining the superior model which is most suitable in a particular context and for the representation of model characteristics. An example is given which will use the approach to evaluate the W-NHPP model and S-shaped model with two group software failure data in our paper (Ⅱ).
