论文摘要
软件可靠性增长模型（SRGMS）基于基本假设，这通常使它们更适合对封闭源项目及其开发生命周期的质量评估。他们在开源软件（OSS）项目中的使用是辩论的主题。尽管确实存在研究SRGMS适用性的研究，但它们受到所考虑的模型和项目数量的限制，这可能会导致不确定的结果。在本文中，我们介绍了SRGMS适用性的实验研究，对总共88个OSS项目进行了比较，比较了9个SRGMS，研究了整个项目中最佳模型的稳定性，在发行版，不同领域以及根据不同项目的属性。借助海峡工具，我们自动化了存储库挖掘，数据处理和SRGM分析，以更好地可重复性。总体而言，我们发现了SRGMS对OSS的良好适用性，但是在将数据集分割为发行版和域时具有不同的性能，突出了在推广发现和搜索单一模型时的困难。
Software Reliability Growth Models (SRGMs) are based on underlying assumptions which make them typically more suited for quality evaluation of closed-source projects and their development lifecycles. Their usage in open-source software (OSS) projects is a subject of debate. Although the studies investigating the SRGMs applicability in OSS context do exist, they are limited by the number of models and projects considered which might lead to inconclusive results. In this paper, we present an experimental study of SRGMs applicability to a total of 88 OSS projects, comparing nine SRGMs, looking at the stability of the best models on the whole projects, on releases, on different domains, and according to different projects' attributes. With the aid of the STRAIT tool, we automated repository mining, data processing, and SRGM analysis for better reproducibility. Overall, we found good applicability of SRGMs to OSS, but with different performance when segmenting the dataset into releases and domains, highlighting the difficulty in generalizing the findings and in the search for one-fits-all models.
