Evaluation of Training Time Sequence based on Workflow Nets

In order to satisfy the demands of evaluation of complex equipment operation training, on the basis of elaborating the characteristics of complex equipment operation training system, the restrictions of the traditional evaluation methods were analyzed, the necessity of time sequence evaluation was proposed. Further, a workflow net model built by using Petri net was described, and the time sequence evaluation criterion corresponding to this model was designed. Finally, by way of virtual training key components example the conduct of form for time sequence evaluation was explained by the aid of the workflow net model, the scientific and validity of the model to training time sequence evaluation was demonstrated.
