“…BGs were first used as a modeling tool, and have gradually been extended to solve various challenges, including fault detection and isolation, observability and controllability [26]. Kumar et al [27] presented a method based on the BG modeling approach for modeling a system of systems (SoS). They argued that the causal and structural properties of the BG can be applied to model the control and supervision of a system.…”

Cyber-Physical Systems (CPSs) engineering profoundly relies on modeling methods to represent the system and study the operation and cybersecurity of CPSs. The operation of a CPS is the result of the collaboration between Information Technology (IT) and Operational Technology (OT) components. While OT focuses on the system's process physics, the emphasis of IT is on information flow. Consequently, different system models are utilized to study various aspects of CPSs, which may infer different views of the same system. The increasing complexity of CPSs and the high number of cyberattacks against Industrial Control Systems (ICSs) and CPSs in recent years have highlighted the necessity of considering these interrelations based on a unified model to analyze cybersecurity of CPSs. However, the diversity of engineering fields and implicit relations and dependencies between them have made it difficult to integrate the modeling methods towards a unified IT&OT model of CPSs.In this paper, we propose a comprehensive method, based on bond graphs, to model CPS and analyze their cybersecurity. Unlike existing methods, modeling the cyber layer along with the physical layer based on the system flow provides a holistic graphical representation of a CPS, which facilitates collaboration between IT and OT experts.

A Software-intensive System-of-Systems (SoS) is architecturally designed to exhibit emergent behavior from the interactions among independent constituent systems. With the upcoming generation of self-driving vehicles, an important case of emergent behavior is vehicle platooning. In a platoon, a group of vehicles (which is dynamically formed) safely travel closely together like in a convoy. It requires, on the one hand, that each vehicle in the platoon control its velocity and the relative distance to the vehicle in front of it for avoiding rear collision and, on the other hand, that vehicles coordinate for enabling other vehicles to dynamically join or leave the platoon. This paper investigates the mediated approach for architecting a platooning of self-driving vehicles, with SosADL, a novel SoS Architecture Description Language (ADL) enhanced with broadcasting for the Internet-of-Vehicles (IoV). In particular, it demonstrates how architectural mediators expressed with broadcast constructs of SosADL for IoV supports platooning architecture descriptions through an excerpt of a real application for architecting platoons of Unmanned Ground Vehicles (UGVs). This novel approach is supported by an integrated toolset for SoS architects.

The pervasiveness of the communication networks increasingly has made possible to interconnect software‐intensive systems that were independently developed, operated, managed, and evolved, yielding a new kind of complex system, that is, a system that is itself composed of systems, the so‐called System‐of‐Systems (SoS). Nowadays, the Internet‐of‐Things (IoT) enables the engineering of software‐intensive SoS, which are opportunistically constructed for achieving specified missions in specific operational environments. In particular, in the subset of IoT where “things” are predominantly connected vehicles, the so‐called Internet‐of‐Vehicles (IoV), the challenge is to exogenously coordinate different vehicles for performing together, through emergent behavior, traffic‐related missions, especially platooning. In platooning, two or more vehicles are connected together in convoy using wireless connectivity and automated driving support. The corresponding challenge in the architectural design of SoSs on IoV is to conceive concepts and mechanisms for describing how an SoS architecture is able to create, on the fly, and maintain emergent behaviors from elementary connected vehicles, where the actual vehicles are not known at design time. To address this challenge, this paper investigates the principle of supervenience for describing architecture‐driven emergent behavior following an exogenous approach. In particular, it describes the concepts and mechanisms underlying SosADL, a formal SoS Architecture Description Language (ADL), based on the novel π‐Calculus for SoS, to support the architectural description of self‐organizing SoSs, upwardly causing the required SoS emergent behaviors at run time. Especially, it demonstrates how architectural mediators expressed with SosADL in exogenous SoS architectures support vehicle platooning through an excerpt of a real application on the IoV.
