摘要:
在原有构件依赖关系的基础上,提出一种架构分析与设计语言(AADL)系统可靠性模型的转换方法。该方法对AADL嵌入式系统体系结构进行可靠性建模,实现AADL可靠性模型到广义随机Petri网(GSPN)可靠性计算模型的转换。研究表明,该方法使AADL可靠性模型向GSPN模型的转换规则更加完备,能对嵌入式系统的可靠性进行准确与全面的分析与评估。

Abstract:
Based on the old component dependencies, this paper presents an Architecture Analysis and Design Language(AADL) system reliability model transformation method. It expands the dependencies to semantic connection, parameter connection and subcomponent calls and realizes the transformation to General Stochastic Petri Nets(GSPN). Therefore, it makes the model transformation rules from AADL reliability model to GSPN model more maturity and realizes exact and entire evaluation to reliability of embedded system.
