ABSTRACT
This chapter presents the basics of Cyber-Physical-Social Systems modelling. To describe the structure of these systems, methods based on multi-agent models have been proposed, with an autonomous agent as the basic element. The basic advantages of multi-agent modelling are described, as well as IT tools to support modelling processes. The following section discusses how to model the processes carried out within the Cyber-Physical-Social Systems. The most widely used process modeling standards are presented, namely, Event-driven Process Chain model; Entity Relationship Diagram; Data Flow Diagram; Petri networks; and Value Stream Mapping. The third part of the chapter presents methods for modelling the risks of loss of process continuity within complex systems of the Cyber-Physical-Social type. A new breakdown of risk sources was proposed from the following perspectives: human resources, financial resources, intangible assets, and infrastructure resources. In the final section of the chapter, a model based on a power distribution is presented as particularly suitable for describing extreme phenomena occurring, for example, in natural disasters.
