摘要:

为了适应民航旅客服务信息系统可靠性要求,针对Schneidewind 模型中对所有失效进行统一处理的不合理情况,结合软件可靠性及其模型的相关理论,提出在Schneidewind 模型中通过加入变点方式来改进模型。该模型利用从软件测试过程中收集到的失效数据,分析民航旅客服务信息系统的可靠性。在民航旅客服务信息系统中引入改进的Schneidewind 模型,并进行实验对比验证。结果表明,文中提出的软件可靠性模型能更好地对民航旅客服务信息系统进行可靠性评估和预测。

关键词: 软件可靠性, Schneidewind 模型, 变点, 失效数据

Abstract:

In order to meet the reliability requirements of civil aviation passenger service information system, it is unreasonable to deal with all the failures in Schneidewind model. Combining with the theory of software reliability and the reliability model, the adding change-point in Schneidewind model is proposed to improve. The failure data collected from software testing process are employed to analyze the reliability of civil aviation passenger service information system, and experiments are carried out to verify the validity of improved Schneidewind model in such a system. Results show that the proposed software reliability model can better evaluate and predict the reliability of civil aviation passenger service information system.

Key words: software reliability, Schneidewind model, change-point, failure data
