A hybrid modeling methodology for cyber physical production systems: framework and key techniques

Cyber-Physical System (CPS) is an emergent approach that focuses on the integration of computational applications with physical devices, being designed as a network of interacting cyber and physical elements. In view of the poor plasticity and non-uniformity of the CPS modeling approach, a comprehensive and integrated design, modeling and representation methodology should continue to be researched. This study presents a conceptual modeling framework (physical, mediator, FBs, agents and holons, PMFAH) and key techniques (CPPS-Mediator, CPPS-Modeler and CPPS-Semantic Processor) aimed at facilitating the design, modeling and representation of Cyber-Physical Production Systems (CPPS), based on employing a hybrid modeling methodology that mainly draws on certain system design paradigms, modeling and representation technologies. Finally, a prototype called CPPS-Tools for supporting CPPS modeling is designed. This paper aims to serve as an important reference for using this framework and key techniques as a basis for developing systematic compositional modeling and analysis schemes for hybrid modeling of CPPS.
