摘要
面对传统认知因素及认知建模所存在的缺陷,以核电厂主控室为参考背景,以人因为关键点,提出了一种基于贝叶斯网络的认知可靠性分析模型。该模型重点分析了影响认知可靠性的人因,对认知节点及认知节点所对应的影响因素提出了一系列方法及相应函数公式来计算认知可靠性。该模型及方法可以应用于核电厂主控室操作人员认知过程的评价。
Facing the shortcomings of the traditional cognitive factors and cognitive model,this paper presents a Bayesian networks cognitive reliability model by taking the main control room as a reference back-ground and human factors as the key points.The model mainly analyzes the cognitive reliability affected by the human factors,and for the cognitive node and influence factors corresponding to cognitive node,a series of methods and function formulas to compute the node cognitive reliability is proposed.The model and cor-responding methods can be applied to the evaluation of cognitive process for the nuclear power plant opera-tors and have a certain significance for the prevention of safety accidents in nuclear power plants.
