摘　　要：为准确描述工作效率对软件可靠性建模的影响,在非齐次泊松过程类软件可靠性增长模型的基础上,提出一种考虑软件测试人员工作效率增长的模型。对软件测试人员的工作效率增长进行建模,定义有效工作时间,结合传统的GoelOkumoto模型,提出基于工作效率度量的软件可靠性增长模型。在ohba,wood以及okumoto这3组真实软件缺陷数据集的验证结果表明,改进模型较G-O模型、Delayed S-shaped模型、Weibull-TEF模型和变型S型-TEF模型表现更优,验证了该方法在软件可靠性评估和预测能力上的有效性。To accurately describe the effects of work efficiency on software reliability modeling,a SRGM with software tester working efficiency improvement by measuring the progress of which during testing process,was proposed based on non-homogeneous Poisson process（NHPP）.By modeling working efficiency of software testers and defining effective working time,a software reliability growth model considering working efficiency measurement was proposed based on the traditional Goel-Okumoto mode.Results of experimental study performed on ohba,wood and okumoto data sets show that the proposed method outperforms G-O,Delayed S-shaped,Weibull-TEF and modified S-TEF,which means it can assess and predict software reliability more accurately.
