摘要: 对现有NHPP类软件可靠性模型进行分析总结,指明了已有NHPP类软件可靠性模型存在的不足及缺陷。综合考虑缺陷探测率、软件运行覆盖率、排除错误时的错误引入率等软件故障数的影响因素,提出了一种通用的NHPP类软件可靠性模型,最后对通用模型中的泛函数取特殊值后,求得期望故障数及软件可靠度,并对其进行分析,证明了所提模型的有效性。

关键词: 通用的NHPP类软件可靠性模型,非完美排错,缺陷探测率,测试覆盖率

Abstract: This paper analyzed the existing non homogeneous Poisson process (NHPP) software reliability model,pointd out the problems and defects of existing NHPP software reliability model.Considering the defect detection rate,coverage,software error introduction rate,the paper proposed a general NHPP software reliability model.Finally,the general model was applied to a set of published failure data,proofing the effectiveness of model.

Key words: General NHPP software reliability model,Imperfect debugging,Defect detection rate,Test coverage
