考虑多种类型缺陷的软件可靠性模型研究

本文提出一种考虑多种类型缺陷的软件可靠性模型,并构建了缺陷检测和剔除两个过程的模型。具体分类情况,可以根据模型的检验方法(拟合准则和预测有效性度量)和模型复杂度来具体决定,如果有测试人员的分类建议或者分类数据,可以结合模型共同决定。为了说明问题,本文给出四种类型缺陷的具体模型,并对实际数据集进行了拟合。通过模型比较,验证了多种类型缺陷模型的有效性。最后,通过构建软件最优发布时间策略对模型进行了应用。研究结果为软件开发和测试提供了理论参考。

Research on Software Reliability Model Considering Multiple Types of Faults

This paper proposes a software reliability model that considers multiple types of defects, and proposes a model for the two processes of defect detection and elimination. The specific classification situation can be specifically determined according to the model's test method (fitting criteria and predictive validity measurement) and model complexity. If there is a tester's classification suggestion or classification data, it can be determined jointly with the model. In order to illustrate the problem, specific models of four types of defects are given, and actual data sets are fitted. Through model comparison, the validity of multiple types of defect models is verified. Finally, the model is applied by constructing the optimal software release time strategy. The research results provide a theoretical reference for software development and testing.
