Method & Evidence

AimHow can a digital twin integrated with a multi-agent cyber-physical system automatically detect anomalies and identify emergent bottlenecks in complex manufacturing systems?

MethodAgent-based simulation and digital twin integration within a cyber-physical system architecture.

ProcedureA multi-agent system with a 'monitoring agent' was developed within a 5C CPS architecture. This system uses agent-based simulation to model the dynamic interactions of micro-level agents (e.g., inventory, human resources) within a digital twin. The monitoring agent detects anomalies and identifies bottlenecks by communicating with other agents, and the digital twin provides automated feedback to the physical system to address these issues.

ContextComplex manufacturing systems, specifically tested in a cryogenic warehouse shop-floor for the cell and gene therapy industry.
