High reliability is an important characteristic of Cyber-Physical Systems (CPS). New CPS components/subsystems have to be developed for the detection, isolation, recovery and prevention of failures and external attacks. To address this challenge, we propose a multi-agent-based subsystem architecture that can detect and prevent CPS hardware components' failures. The architecture comprises of several...
Cyber-Physical Systems (CPSs) represent a new generation of engineered systems facing significant scientific challenges in terms of modeling, architecture, distributed computations and network control, verification/validation mechanisms, and many others. CPSs modeling, a significant aspect of their design and development, can be performed using the Model-Driven Engineering (MDE) paradigm. This approach...
Cyber-Physical Systems (CPSs) represent a new generation of digital systems, where cyber entities and physical devices cooperate towards a set of common goals. The research presented in this paper aims to contribute to the development of CPSs by proposing: (1) an analysis methodology to model the CPS’s behavior in terms of dependability; and (2) a CPS architecture with dependability facilities applicable...
Cyber-Physical Systems (CPSs) represent a new generation of digital systems, where cyber entities and physical devices cooperate towards a set of common goals. The continuously evolving requirements concerning CPSs have led to the necessity of creating a dependability assurance framework. The present paper introduces a methodology for creating a dependability run-time model of CPSs in a dynamic and...
