摘要 操作员认知行为的计算机模拟是人为因素研究和人机系统评估的一种有前途的方法。本文提出了一种基于当前人工智能技术的模拟架构。该仿真系统利用真理维护系统构建为基于知识的黑板模型系统，能够很好地体现人类思维的可修正性。通过对该系统的信息处理活动进行评分来尝试评估操作员的认知工作量。每种类型的活动分别进行评分。对核电厂异常工况运行的一些情况进行了试验模拟。在案例研究中，进行了错误机制的调查和认知负荷的评估。
Abstract Computer simulation of an operator's cognitive behavior is a promising approach for the purpose of human factors study and man-machine systems assessment. In this paper an architecture of the simulation is proposed, based on the current AI technologies. The simulation system has been constructed as a knowledge-based system of the blackboard model, which can represent well the revisable nature of human thought, by use of the Truth Maintenance System. Assessment of cognitive workload imposed on an operator was attempted by scoring information-processing activities of this system. The scoring was done separately for each type of activity. A test simulation was performed on some cases of nuclear power plant operation under abnormal plant conditions. In the case study, investigation of the mechanism of mistakes and assessment of the cognitive workload were performed.
