Ontological Engineering of Interrelated Processes in Complex Cyber-Physical Systems

Abstract

The processes in complex cyber-physical system are always interrelated, which means different processes share the same information. Such sharing requires the robust approach to create, update and maintain the ontologies of processes and cyber-physical system as a whole in order to create well-organized data structure and to avoid duplication of information. The resulting complete ontology of cyber-physical system should be a convenient and flexible basis for modeling processes and ensuring the functioning of information-analytical and system processes. Metagraphs are considered as the basis for building an applied system ontology and extracting the ontologies of processes. A modification of the metagraph is proposed to include events and system methods in the ontology. This approach to the construction of a metagraph allows to include the process component in the ontological model of the system as an integral part of it, which allows to flexibly and with lower time expenses design, update and maintain process models based on segments of the general ontological model. As a basis for modeling, it is proposed to use a temporal neuro-fuzzy variety of Petri nets. An example of the implementation of a software-instrumental environment for ontological engineering and further construction of models of processes of a complex cyber-physical system is presented.
