Digital twin types: (1) Digital twin prototype (DTP) - design + simulation phase. (2) Digital twin instance (DTI) - operational + real-time. (3) Digital twin aggregate (DTA) - fleet / multiple instances.

Use cases: (1) Design + engineering - virtual commissioning, what-if analysis. (2) Manufacturing execution - production monitoring, OEE optimization. (3) Predictive maintenance - failure prediction, condition-based maintenance. (4) Quality control - defect detection, traceability. (5) Logistics + supply chain - asset tracking, reverse logistics. (6) Sustainability - carbon footprint tracking, energy optimization.

Reference architecture (ISO 23247 Part 2): 4 layers - (1) Physical layer (sensors, actuators, machines). (2) Communication layer (OPC UA, MQTT, REST). (3) Information layer (data ingestion, processing). (4) Application layer (analytics, ML, decision support).
