Integrated modeling method of Cyber physical system based on extended AADL

Abstract The concept and connotation of CPS are analyzed firstly in the paper, then the challenges of system modeling brought by heterogeneous feature of the CPS system are pointed out. How to describe the CPS model are studied. We propose a description method of CPS integrated modeling framework based on extended AADL (architecture analysis and design language); and realize the unified description of the computing entity, the physical entity and interactive entity through extending the standard and appendix of AADL.
