摘　　要：情景意识是核电厂操纵员可靠性研究的基础,HRA理论依赖于一个合理的情景意识评价模型。操纵员情景意识始于组织触发层,通过操纵员的认知与核电厂系统发生交互作用。本文首先确立情景意识与HRA之间的关系,建立组织定向的情景意识因果概念模型。在此基础之上,使用贝叶斯网络建立核电厂操纵员情景意识评价模型,进行因果推理和诊断推理。该方法不仅能计算给定证据条件下,对操纵员情景意识进行评价,而且能定量识别出操纵员情景意识中主要的影响因素。Operators＇ Situation awareness plays a key role in the safety of a nuclear power plant. Human reliability analysis theory heavily depends on a reasonable situation awareness assessment model. Operator＇s situation awareness starts at organization level and interfaces with plant system at the level of operators＇ cognition. This paper firstly examines the relationship between situation awareness and human reliability analysis. It then establishes an organization-committed casual model. Accordingly, Bayesian network is used to assess operators＇ situation awareness. The method can not only assess the situation awareness in the case of given evidence but also identify the main influencing factors of operators＇ situation awareness.
