> 中文摘要: 主要针对AADL(architecture analysis and design language)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(general stochastic Petri net,简称GSPN)可靠性计算模型的转换,并基于GSPN 可靠性计算模型对嵌入式系统进行可靠性评估.为了支持可靠性分析评估过程的自动化,根据模型转换的形式化方法,设计并实现了AADL 可靠性评估工具(AADL reliability assessment model tool,简称ARAM),该工具集成在AADL 体系结构设计工具OSATE(the open source AADL tool environment)中,并内置Petri 网计算工具PIPE2(platform independent Petri net editor 2),实现基于GSPN 模型的可靠性分析评估.同时,结合航空飞行控制系统的可靠性分析评估介绍了ARAM 工具的应用情况.
Abstract:This paper focuses on a reliability model of embedded system architecture using AADL (architecture analysis and design language). It performs transformation from AADL reliability model to GSPN (general stochastic Petri net) model and assesses AADL architecture reliability computation model by the means of GSPN theory. To support the reliability analysis and assessment automatically, this paper designs and implements an AADL reliability assessment model tool, ARAM (AADL reliability assessment model tool), with formal methods. It is integrated into OSATE (the open source AADL tool environment) and uses PIPE2 (platform independent Petri net editor 2) to carry out the reliability assessment of GSPN model. Meanwhile, this paper also presents a case study on the reliability analysis and assessment of avionics flight control system to demonstrate the performance of ARAM.
