| 摘 要： | 针对现有的NHPP类软件可靠性增长模型,提出一个既考虑关联故障和构件结构,又考虑软件的不完美测试、故障检测率和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.许多经典的软件可靠性增长模型以及基于软件故障类型和构件结构的NHPP类模型都可以从这个框架中推导出来.

| Abstract: | Aimed at the present NHPP software reliability growth models,an improved framework of NHPP software reliability growth model,in which both the fault correlations as well as software components construction and imperfect software debugging,time-dependent fault detection rate,and time-dependent fault removal efficiency were taken into consideration.Many existing NHPP software reliability growth models and software fault mode-and component structure-based NHPP-type models could be derived from this frame. |

| Keywords: | software reliability growth model non-homogeneous Poisson process correlative fault software component structure |
