This paper describes CYBERBIKES, a real-time simulation of an enterprise that produces bicycles. The system is designed as a virtual environment. It is based on a realistic 3-D model of an industrial enterprise coupled with the representation and control of production processes. Furthermore, the flow of information like production data is visualized by means of clear metaphors. The user is immersed in the virtual environment by using a head mounted display through which he/she can explore the various departments of the industrial enterprise and learn how information technology influences modern production processes. This system is intended to train students of industrial engineering in the workings of a modern industrial enterprise. It will also be used for research in production technology as well as in the practical study of virtual reality technology.
