摘　　要：随着基于构件的软件开发模式的迅速发展,传统的NHPP模型无法适应大型的基于软构件的新型软件开发模式。结合软件可靠性分析中的黑盒方法和白盒方法,提出一种基于构件的NHPP类软件可靠性增长模型,CB-NHPP模型。该模型以可加模型为基础,实现了时间域模型和体系结构域模型的结合,克服了这两种技术无法同时考虑软件测试过程中的故障排除和软件体系结构的问题。由于同时考虑了更多因素,因此该模型具有更高的准确性。最后通过实验证明了CB-NHPP模型的有效性。With the rapid development in component-based software development patterns, traditional NHPP models can＇t adapt themselves to the new large component-based software development patterns. A component-based software reliability growth model, CB-NHPP model, was proposed by combining black-box methods with white-box methods in software reliability analysis. Based on additive model, CB-NHPP model integrates time domain models with structure domain models to simultaneously address system structures and software with repair. This model is more precise because it considers more factors. At last an example is evaluated to validate and show the effectiveness of CB-NHPP model.
