基于任务-网络模型的装甲车辆乘员脑力负荷评价方法研究

Research on Evaluation Method of Armored Vehicle Crew's Mental Workload Based on Task-network Model

以多资源理论(MRT)为基础,充分考虑装甲车辆乘员作业特点,从人的信息处理方式入手建立了基于信息执行通道的乘员任务-网络模型,提出了基于任务-网络模型的装甲车辆乘员脑力负荷评价方法。以装甲车辆炮长发现目标并射击任务操作为实例进行分析评价,结果表明,该方法能够清楚地描述乘员全任务过程中脑力负荷的变化情况,有效地找出脑力负荷异常的时间节点和产生原因,量化评估乘员的脑力负荷。

A method of evaluating the mental workload of armored vehicle crew based on task-network model is proposed based on multiple resource theory （MRT） , and a crew＇s task-network model based on information executive channel is built in terms of information processing method under consideration of armored vehicle crew＇s operation characteristics. An example of target discovering and firing task of an armored vehicle gunner is analyzed and evaluated. The results indicate that the proposed method could describe the change of crew＇s mental workload during the whole task. The time nodes and reasons of abnormal mental workload could be found out effectively using the proposed method and the mental workload of crew could be quantitatively evaluated.
