Abstract:
Cyber-physical systems (CPS) require precise interaction modeling and rigorous verification to guarantee reliability and correctness, particularly in safety-critical systems, where interaction errors such as deadlocks may lead to critical failures. Although SysML v2 provides expressive modeling capabilities, it lacks explicit execution semantics for structured interactions. To address this limitation, we propose a structured subset of SysML v2 to specify interactions at the structural level. These interactions are then mapped to the Behavior, Interaction, Priority (BIP) framework, which defines their execution semantics and enables formal analysis. Specifically, we introduce Rendez-vous and Broadcast connectors to enforce synchronization and one-to-many communication, respectively, ensuring that interactions are explicitly represented and amenable to formal analysis. BIP provides precise execution semantics, facilitating rigorous verification and streamlining the process by eliminati
ng the need for external verification models. We validate our approach through a case study on swarm drone coordination, demonstrating structured execution, the ability to detect and resolve critical deadlocks, and the correctness and robustness of interactions.
