摘要:

随着软件质量的提高,对软件可靠性的要求也越来越高。目前已经有一百多种软件可靠性模型。然而,在实际应用中由于可操作性等因素的影响,大多模型都没法得到有效的应用。鉴于此,本文在Nelson模型的基础上,结合Bayes原理给出了一种新的衡量软件可靠性的简单方法。实验表明,改进后的模型在实际应用中有较好的效果。

关键词: 软件可靠性模型 测试域 测试用例 失效数据

Abstract:

Software reliability becomes very important with the demand of software quality increasing. Until now there are more than one hundred models,but in th e actual applications,because of the operational and other factors, it is hard to apply them effectively. So a new software model is presented based on   the Nelson model by Bayes. Finally, experimental results show that the model has better effect than the Nelson method.

Key words: (software reliability model, test domain, test case, failure data)
