摘要: 软件可靠性评估可以估计和预计软件可靠性水平.为了解决软件可靠性预计过程中存在的问题,提出了一种软件可靠性预计方法.该方法通过分析和改进模型的预计质量来选择模型进行预计,对模型预计质量的分析使用了U图、Y图和对数PLR图,再标定法和组合法被用于改进模型的预计质量.在该方法的基础上开发了软件可靠性分析工具,此工具可以进行多种软件可靠性模型的原始预计、预计质量分析和改进原始模型的预计质量.

Abstract: Software-reliability evaluation can estimate and predict reliabilities of software . For the purpose of solving the problems in software prediction process, a practical software-reliability prediction method is proposed to give better software reliability predictions. In this method, a model is selected by analyzing and improving models' prediction quality. U plot, Y  plot and logarithm PLR plot are used to analyze models' prediction quality,recalibration method and combination method are used to improve it. A software-reliability analysis tool based on this method is then developed. With this tool one can do predictions using several kinds of raw software reliability models, analyze prediction quality and improve prediction quality of raw models.
