Abstract: Existing methods are difficult to solve dynamic evaluation problems in the process of virtual training. Based on existing methods, time serial factor is introduced to present dynamic evaluation model. In this model, time-step method and event-step method are combining to establish three-dimentional sequencing evalution matrix (evaluation object,evaluation time, evaluation index). To solve this matrix,this paper extends the ordered weighted averaging(OWA) operator to weighted evaluation function and presents time ordered weighted averaging function for process-oriented virtual training. In this way, dynamic evalution problems for training process are solved satisfactorily. Finally, the mothed is applied to virtual training system of certain machinery and realizes dynamic evaluation and visualization of the evaluation process.
