在现代社会，软件无处不在，我们需要可靠的软件。在实践中，在软件开发过程中，软件可靠性评估可以极大地帮助管理人员了解所消耗的测试工作的有效性，并部署测试资源。从20世纪70年代到2000年，人们提出了许多软件可靠性增长模型（SRGMs）来估计软件产品的可靠性增长。由于测试资源的消耗现象可能在某些时刻发生变化，因此本文将多变更点的概念引入weibull型测试工作量依赖的SRGM中。通过一个实际数据集验证了所提模型的性能和应用。实验结果表明，该模型具有较好的故障预测效果。此外，还讨论了基于可靠性要求和成本准则的最优放行时间问题。
In modern societies, software is everywhere and we need software to be reliable. In practice, during software development processes, software reliability assessment can greatly help managers to understand effectiveness of consumed testing-effort and deploy testing-resource. In the 1970s-2000, many software reliability growth models (SRGMs) have been proposed for estimation of reliability growth of software products. In this paper, the concept of multiple change-points is incorporated into Weibull-type testing-effort dependent SRGM because the consumption phenomenon of testing resource may vary at some moments. The performance and application of proposed models are demonstrated through one real data set. The experimental results show that the models give an excellence performance on failure prediction. Besides, we also discuss the optimal release time problems based on reliability requirement and cost criteria.
