基于量化故障分析的软件可靠性研究

介绍一种基于故障等级分析的软件可靠性评估方法．这种方法利用软件系统测试后得到的缺陷数据，对每一个缺陷导致失效的内外因进行分析，算出每个缺陷的失效率。将失效数据进行分级，在失效率小的等级中进行故障注入，试验结果表明。将软件可信性定位在正确性、可靠性、容错性、安全性、隐私性这5个要素进行评估。评估的有效性和合理性不亚于传统的方法，大大提高软件开发的质量和效率。

Research on Software Reliability Assessment Based on Rank Analysis of Fault

Introduces a method of software reliability evaluation based on fault level analysis. Makes use of the defect data obtained after the test software system,analyses each defect bringing about failure from inner and outer factor,and calculates failure rate of each defect. The failure data classification, fault injection in the failure rate of small scale,the experimental data shows that focuses on five aspects of trustworthiness, improves software development quality and efficiency. The validity and flexibility is at least as efficient and reasonable as the conventional test, and improves software development quality and efficiency.
