The integration of 3D visualization is a feasible and effective strategy for the performance and quality improvement of current discrete event simulation technology. 3D visualization helps users to understand the simulation system more effectively, allows to visually analyze large sets of simulation related information and improves confidence while studying and analysing the simulation results. This paper describes the design and development of a virtual 3D visual simulation environment for modelling and simulation of supply chain networks. The virtual environment provides a unified framework for development and representing of simulation models in 3D encapsulating the static and the dynamic behaviour of the supply chain system.
