摘　　要：针对基于有限排队系统的软件可靠性增长模型(SRGM)忽略软件交付与检测之间的时间延迟问题,提出双排队系统建模技术,构建一个引入故障检测等待延迟和排错等待延迟的SRGM。建模中考虑测试工作量函数(TEF)参与构成的复合型故障检测率(FDR)和不完美排错现象,在4个公开发表的失效数据集上与5个经典SRGM进行比较与分析,验证建立模型的拟合能力和预测能力。实验结果表明,建立的模型在软件可靠性评估和预测方面具有良好性能。Aiming at the problem that the software reliability growth model(SRGM) based on finite queuing system ignores the time delay between software delivery and detection, a double queuing system modeling technology was proposed, and a SRGM with fault detection waiting delay and debugging waiting delay was constructed. In the modeling, the compound fault detection rate(FDR) composed of testing effort function(TEF) and imperfect debugging phenomenon was considered. The fitting ability and prediction ability of the model were verified by comparing and analyzing with five classical SRGM on four published failure datasets. Experimental results show that the established model has good performance in software reliability evaluation and prediction.
