Human Digital Twin for integrating human workers in Industry 4.0
A proposal for representing the human as a first-class “digital twin” entity—so tasks, constraints, and interaction can be coordinated like any other system resource.

Digital twins are widely used for machines and processes—but a factory is also constrained by human capabilities, workload, skills, and availability. If the system can’t represent those human realities, it struggles to assign work safely and effectively.
This conference paper introduces the concept of a Human Digital Twin as a structured representation of the worker that can be integrated into Industry 4.0 coordination. The aim is to enable better task allocation and interaction by treating the human as a modeled system participant rather than an external “exception handler”.
Key takeaways
- Human integration improves when the human is represented explicitly, not implicitly.
- A Human Digital Twin supports coordination and traceability around skills, workload, and constraints.
- Modeling humans as first-class entities is a prerequisite for worker-centric automation.
