Abstract
With the rapid development of integrated modular avionics (IMA), the dynamic reconfiguration of IMA provides great advantages in resource utilization and aircraft configuration and acts as a valid means for resource failure management. Due to the complexity of dynamic reconfiguration process, it is difficult to analyze and evaluate the safety of dynamic reconfiguration process. The Architecture Analysis and Design Language (AADL) is effective in modeling such process of the embedded real-time system. Colored Petri Net (CPN) has advantages of simulation and evaluation. Therefore, this paper model the IMA dynamic reconfiguration process based on AADL, and transfer it to CPN model to analyze and evaluate the safety of the process of dynamic reconfiguration. Finally, a case study is provided to indicate the effectiveness of the method.
