Abstract: The effective cognitive model is a key technology to study the information processing work state of armored vehicle crew and enhances the combat effectiveness of man-machine system. In view of the basic trend of transforming the physical operating task to information processing task，the operatal units are systematically analyzed，the cognitive elements are extracted based on multi-resource theory(MRT), a cognitive model is established based on task-network，and the objective-subjective verification process for crew's cognitive model is proposed. The model is verified through example, with an aim to solve the problem of cognitive modeling. The results indicate that the proposed model could be used to describe the whole cognitive process of crew's information processing task, and predict the reaction times of operatal units accurately. It has high prediction accuracy and reusability preferable. It is an effective and feasible approach for crew's cognitive modeling. Key
