软件系统故障传播模型研究进展

Research Progress on Error Propagation Model in Software System

复杂软件系统的复杂性和不确定性引起了软件行为、交互行为以及故障行为的复杂性。在对复杂软件系统的可靠性、安全性等方面研究的过程中,故障的传播行为逐渐引起了学者的广泛关注,成为国内外学者的研究热点。回顾了故障传播的研究现状,对故障传播问题研究方向进行了梳理,重点对影响故障传播过程的两方面进行了详细的介绍,包括体系结构特征和故障类型。最后提出故障传播研究领域存在的挑战和未来的研究方向。

The complexity and uncertainty of complex software system bring about the complexity of software beha- vior,interaction,and error behavior. In the research process of complex software system reliability, security and other fields,error propagation has been a research focus, which attracts wide attention of domestic and overseas scholars. Firstly,the latest development of error propagation was summarized. Then the research direction of error propagation was presented. What＇s more, this paper compared and analyzed the factors affecting error propagation, including system architectural characteristics and fault type. Finally, the challenges and future research of error propagation were pro- posed.
