基于故障等级分析的软件可靠性评估方法研究

Software Reliability Assessment Based on Rank Analysis of Fault

介绍了一种基于故障等级分析的软件可靠性评估方法,这种方法利用了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,该方法将软件可信性定位在正确性、可靠性、容错性、安全性、隐私性,通过这五个要素的评估。评估的有效性和合理性不亚于传统的方法,大大提高了软件开发的质量和效率。

A method of software reliability evaluation based on analyzing of Fault level is introduced. Firstly, this method makes use of the defect data obtained after the test software system, each defect bringing about failure is analyzed from inner and outer factors, and then failure rate of each defect is calculated. In this paper, the failure data classification, fault injection in the failure rate of small scale. The ex- perimental data shows this paper focuses on five aspect s of t rustwort hiness, improve software development quality and efficiency. The valid- ity and flexibility is at least as efficient and reasonable as the conventional test, and improving software development quality and efficiency.
