Because of this reason , it is important to implement measurable management work based on software reliability in software projects . software reliability is the most important quality characteristic and easy to be measured . software is dynamic , so it suit to evaluate and predict software development process 这主要是因为: ( 1 )软件可靠性是软件质量最重要的特性,也被证实是软件质量中最容易定量的特性; ( 2 )软件可靠性是动态变化的,因此非常适用于评估软件开发过程,并根据可靠性预测进行项目的费用估算和进度安排; ( 3 )软件可靠性预测模型是定量评估和预测软件可靠性的基础。
Reliability prediction precision is not better in the traditional software reliability prediction models . in order to resolve this problem , semi - analytical prediction method is established in this paper . the new method combines artificial neural network ( ann ) and reliability growth model 笔者先对传统预测模型进行了介绍和评述,指出采用传统方法,模型在预测精度上均有待提高,为了解决这一问题,笔者将人工神经网络技术应用于软件可靠性增长模型(解析模型)中,提出了软件可靠性预测的半解析方法。
