Different virtual educational experiments (VEEs) have different frameworks and implementations in different disciplines. How to integrate different VEEs into one unified supporting platform is a challenging problem. The key problem of this integration is how to build a unified mathematical model for VEEs of diversified disciplines. However, most existing multi-domain uniform modeling (MDUM) approaches such as Modelica are research-oriented and lack of real time interaction, which does not meet the requirement of virtual experiments that are user-oriented and highly interactive. To tackle above problem, a Modelica-based interactive scheduling mechanism (MISM) for VEE is proposed. In MISM, user-oriented interaction is based on a best step length algorithm and an interactive event step algorithm. The throughput is considered in the former and the real time interaction is resolved by the latter. Experimental results shows that the approaches presented can meet the requirements of VEEs efficiently.
