| 摘 要： | 软件可靠性增长模型是用来评估和预测软件可靠性的重要工具.目前,绝大多数的软件可靠性增长模型并没有考虑故障之间的相关性,也没有考虑测试环境和运行环境的区别.文中提出了一种随机过程类非齐次泊松过程(NHPP)中的考虑故障相关性、测试环境和运行环境差别的模型.在两组失效数据上的实验分析表明:对这两组失效数据,文中提出的模型比其他一些非齐次泊松过程类模型的拟合效果和预测效果更好.

| Abstract: | Software reliability growth model(SRGM) is one of the important tools to evaluate and predict software reliability.However,software failure dependency,the differences of testing environment and operational environment are not considered by most SRGMs.This paper proposes a software reliability growth model that consider software failure dependency and differences of testing and operational environment.The experimental results based on two failure data sets show that the proposed model has better predictive power and curve fit than other NHPP SRGMs. |
