摘要
结合N-back任务范式和持续操作测试(CPT)任务范式,设计出模拟认知性VDT持续监控作业的实验.根据实验数据:分别对脑力负荷评估指标体系中的6个评估指标在20个作业时间段的均值进行方差分析,差异显著;训练非线性自回归神经网络模型(NAR),对不同作业时间段脑力负荷在评估指标上发生的变化进行动态预测;再结合认知性VDT持续监控作业人因可靠性评估模型对人因可靠性概率进行预测.研究结果表明:该方法可动态预测不同时间段作业者的人因可靠性,实现认知性VDT持续监控作业任务的动态分配,提高系统可靠性.
The experiment was designed base on N-back paradigm and CPT paradigm, which can simulate cognitive monitoring tasks. By using variance analysis method, we found that the mean values of the 6 mental workload assessment indicators were significantly different in the 20 working time periods. 6 nonlinear auto regressive(NAR) networks were trained for dynamic prediction of 6 indicators' value, and then the possibility of human reliability could be predicted by combining the human reliability evaluation model. The result shows that the method can predict the human reliability and assign task of VDT cognitive monitoring operating systems dynamically.
