摘　　要：可靠性作为衡量软件质量的重要特性,其定量评估和预测已成为人们关注和研究的焦点。软件可靠性模型既是软件可靠性定量分析的基础,也是可靠性预测的核心和关键。在软件比重日益增加的今天,研究系统的软件可靠性对整个产品质量的提升具有很大的现实意义。现有的软件可靠性模型大都是基于概率统计建立的,考虑的因素比较单一,与工程实际有一定差别。文中对典型的软件可靠性模型进行比较研究,在综合考虑了输入域、缺陷等级、时间域等因素的基础上,经过严密的数学推导,建立了基于测试用例和时间域的软件可靠性混合模型,并对该模型的实际应用进行了介绍。The reliability as the software quality＇s important characteristic, its quantitative assessment and the forecast has become the focal point. The software reliable model is not only the software reliable quantitative analysis foundation, but also the reliable forecast core and the key. Today in the software proportion, the research system＇s software reliability has the very big practical significance to the entire product quality＇s promotion. Most of the software reliability modules are based on probability and statistics. They consider less elements. There are relatively big gap between these modules and practical project. After analyzing and comparing typical software reliability modules, proposed a new software reliability module, using mathematical knowledge. This module is based on inputting domain, error level and time domain. Also introduce the application of the module briefly.
