摘要
NHPP类软件可靠性增长模型已经成为软件可靠性工程实践中非常成功的工具,从某些模型的一些共同特征出发,研究了NHPP类软件可靠性增长模型的有限通用框架,提出了一个既考虑软件测试的不完美性、故障检测率随时间的变化,又考虑了故障改正效率随时间变化的NHPP类软件可靠性增长模型框架。一些已经存在的NHPP类软件可靠性增长模型是这个框架的特例。
Software reliability growth models based on the NHPP (non-homogeneous Poisson process) have been quite successful tools in practical software reliability engineering. The common features of some NHPP software reliability growth models and some general NHPP models are studied. A general NHPP model is proposed, which considers imperfect software debugging, time-dependent fault detection rate, and time-dependent fault removal efficiency. Many existing NHPP software reliability growth models are special cases of the general NHPP model.
