Abstract

AADL is a common method for modeling and evaluating SA in the embedded field, but AADL is a semi-formal development language, cannot directly verify reliability of SA. Therefore, this paper developed a reliability analysis framework based on AADL to formally verify the reliability of SA. Firstly, it built AADL reliability model of architecture by analyzing the relationship of system architecture elements. Then, it designed the transformation model and its rules to transform the AADL model into the continuous time Markov chain model. Finally, it used probabilistic model test to quantitatively analyze the reliability of continuous time Markov chain model. Simulation results show that, compared with existing reliability analysis methods, this method has significantly improved the computational efficiency and conversion efficiency. Reliability analysis frame-work based on AADL realizes the quantitative calculation of SA reliability in the early stage of software system development, and provides a new verification idea for AADL in the quantitative analysis of embedded software system reliability.
