摘要
为解决虚拟训练过程中动态评价难的问题,在静态评价基础上,引入时序因子,构建了虚拟训练动态评价模型,在该模型中,使用时间步长和事件步长相结合的方法建立了由对象、时间、指标组成的三维排序评价矩阵;将有序加权算子(OWA)和权重评判函数相结合,提出了面向虚拟训练过程的时序平均加权函数,使用该函数对三维排序评价矩阵进行求解,完成了面向虚拟训练过程的动态评价。最后,将该方法应用于某型工程机械虚拟训练系统中,实现了虚拟训练过程的训练效果动态评价及评价过程的可视化。
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 sequ thi ncing evalution matrix (evaluation object,evaluation time, evaluation index). To solve this matrix paper extends the ordered weighted averaging(OWA) operator to weighted evaluation function 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.
