Software reliability literature consists of various change-point-based software reliability growth models and related release time problems. The primary assumption of the existing models is the existence of change-point before software release time only. This does not look practical as the testing team becomes more proficient in detecting the faults due to their continuous involvement in software development by the software release time. Hence the fault detection rate in the pre- and postrelease phase is not the same. To capture this change in fault detection rate in the pre- and postrelease testing phase, we propose a new software reliability modeling framework by considering two change-points during the software lifecycle; that is, there exists a change-point before release time and release time as a change-point. Further, in the last one-decade software firms have changed their strategy of stop testing the software after release and continue to test even after release to remove the number of faults to provide better user experiences. This phenomenon attracted academicians to develop theoretical as well empirical study on postrelease testing and formulation of related release time problem. In this paper, we propose a software cost model to determine optimal release and testing stop time considering under the assumption of two change-points as mentioned above. The proposed model is validated on real-life data set.

基于变更点的软件调度

软件可靠性文献包括各种基于变化点的软件可靠性增长模型和相关的发布时间问题。现有模型的主要假设是仅在软件发布时间之前存在变更点。这看起来不切实际，因为测试团队在软件发布时持续参与软件开发，从而更加精通检测故障。因此，发布前和发布后阶段的故障检测率并不相同。为了在发布前和发布后测试阶段捕捉故障检测率的这种变化，我们通过考虑软件生命周期中的两个变化点，提出了一种新的软件可靠性建模框架；即在发布时间之前存在一个变化点，发布时间作为一个变化点。更远，在过去的十年中，软件公司改变了发布后停止测试软件并在发布后继续测试的策略，以消除错误数量以提供更好的用户体验。这一现象吸引了院士们对发布后测试和相关发布时间问题的制定进行理论和实证研究。在本文中，我们提出了一个软件成本模型，以确定在上述两个变化点假设下的最佳发布和测试停止时间。所提出的模型在现实生活中的数据集上得到了验证。这一现象吸引了院士们对发布后测试和相关发布时间问题的制定进行理论和实证研究。在本文中，我们提出了一个软件成本模型，以确定在上述两个变化点假设下的最佳发布和测试停止时间。所提出的模型在现实生活中的数据集上得到了验证。这一现象吸引了院士们对发布后测试和相关发布时间问题的制定进行理论和实证研究。在本文中，我们提出了一个软件成本模型，以确定在上述两个变化点假设下的最佳发布和测试停止时间。所提出的模型在现实生活中的数据集上得到了验证。
