CAPS: Architecture Description of Situational Aware Cyber Physical Systems

Abstract

This paper proposes CAPS, an architecture-drivenmodeling framework for the development of Situational AwareCyber-Physical Systems. Situational Awareness involves being aware of what ishappening in the surroundings, and using this informationto decide and act. It has been recognized as a critical, yet often elusive, foundation for successful decision-makingin complex systems. With the advent of cyber-physical systems(CPS), situational awareness is playing an increasinglyimportant role especially in crowd and fleets management, infrastructure monitoring, and smart city applications. Whilespecializing cyber physical systems, Situational Aware CPSrequires the continuous monitoring of environmental conditionsand events with respect to time and space. New architecturalconcerns arise, especially related to the sense, compute &communication paradigm, the use of domain-specific hardwarecomponents, and the cyber-physical space dimension. This work illustrates the CAPS modeling languages usedto describe the software architecture, hardware configuration, and physical space views for a situational aware CPS.
