This paper proposes an orchestrator framework for reproducing complex disaster phenomena. Our orchestrator framework, based on the CyReal concept, integrates multiple simulators and systems through a federation bus, and enables effective collaboration and coordination among them using data exchange functions and time synchronization mechanisms. This framework allows for flexible integration of different types of simulators, enabling simultaneous modeling of diverse elements such as disaster phenomena, human behavior, and infrastructure conditions. The framework’s performance was evaluated through load and scalability tests of a prototype, demonstrating its ability to handle increases in data volume and processing of multiple simulators with minimal impact. The prototype using simplified simulators represents a significant step towards creating a comprehensive cyber-physical system capable of addressing more complex disaster scenarios.
