Specification and Design of Cyber Physical Systems Based on System of Systems Engineering Approach

Abstract

Cyber-physical Systems of Systems (CPSoS) are large complex systems where physical elements interact with and are controlled by a large number of distributed and net-worked computing elements and human users. A SoS is an integration of a finite number of constituent systems which are independent and operable, and which are networked together for a period of time to achieve a certain higher goal. In order to specify and model such kind of systems, we need develop specification and modeling methods which would be capable to encompass the systems of systems (SoS) specific properties of cyber physical systems. In this paper, we propose a new paradigm for specifying and modeling cyber physical systems based on system-of-systems approach. We propose an approach to support specification and modeling cyber physical systems based on systems of systems engineering by integrating AADL, Modelicalml and other modeling language. On the basis of the hierarchical concept of industrial CPS system, a hierarchical design scheme of industrial CPSoS system based on OPC UA heterogeneous data integration processing is proposed. This paper will also use AADL for modeling CPS on three levels: 1). robot on the unit level; 2) workshops of smart factory on the system level 3) intellectual factory on the SOS level. For the physical aspect of cyber physical system, this paper will propose a method to combine modelical, Simulink and AADL model to model a unit robot which can interaction with real environment.
