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

doi:10.3969/j.issn.1000-1093.2015.09.028

Abstract

Abstract: 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.

Key words: ordnance science and technology, armored vehicle, multiple resource theory, task-network model, mental workload
