摘要:
Endsley (1995) systematically put forward the theory of Situation Awareness (SA). The theory emphasizes people’s perception and understanding of current operating environment information, and prediction of future state under certain time and space conditions. Endsley and Jones (2012) further proposed a SA-Oriented Design system. With the deepening of SA research, it has become the frontier of engineering psychology research. At present, Nuclear Power Plants (NPP) are highly computerized, the complexity of its main control room has increased, man-machine interaction is frequent, tasks are complex and changeable, time pressure is high, and cognitive load is heavy, so the workload of operators is greatly increased. In this complex technical system, the accuracy of Team Situation Awareness (TSA) of NPP is an important factor for high quality decision-making and efficient operation. If the problem of real-time and accurate SA measurement can be solved, it will be helpful to the design of Real-Time Adaptive man-machine interaction. Firstly, this paper analyses the elements and types of Team Situation Awareness of nuclear power plant, and develops a team SA measurement scale. Then, in different accident scenarios, the level of team SA of different types was measured by the simulation experiment, and the influencing factors were analyzed. These provide theoretical and experimental support for improving TSA of NPP.

摘要:
Situation awareness (SA) reliability of operators is an important component of human reliability analysis (HRA) in digital nuclear power plants (NPPs). Therefore, how to identify effectively and reliably the risk of SA errors is of great significance for SA error prevention and risk reduction. SA reliability assessment model or method based on fuzzy logic and analytic hierarchy process (AHP) is forwarded in the first paper. In order to prove its effectiveness and reliability, sensitivity analysis and simulator experiments are applied to testify our model in this paper. The results show that the proposed assessment model of SA reliability has a certain degree of sensitivity as well as an accuracy of prediction, and there are a strong correlation and consistency between the predicted value from fuzzy inference system and the real value (or observed value) from simulator experiments. Although there are some differences between the predicted value and the real value based on the perspective of HRA, the model can be used to predict SA error probability or SA reliability within the range of 10 error factors as well as provide data and theoretical support for SA reliability assessment.

摘要:
Is EOM behavior a stochastic process? If it is, does this randomness come with certain conditions? Are there some environmental factors playing a role? Does the failure of EOMs can be expressed by a probability number? How should HRA consider EOM in a framework of PSA? Through the experiments on a DCS simulator of a nuclear power plant, the researchers tried to come up answers to the above issues. The research results show that the EOM behavior of nuclear power plant is random no considering the influence factors, while in the case of data groupings, EOM behavior is not completely random. Some factors, such as age, training time and working hours, have a certain influence on the randomness of EOM behavior, which also provides direction for reducing human error. Of course, due to the limitations of the experimental conditions, the correctness of the conclusion remains to be further verified.

摘要:
In digital control rooms, situation awareness (SA) reliability has become an important element affecting operator's reliability. In order to establish a more reasonable assessment method of SA reliability under the condition of very lack of data, based on the established influential factor model of SA reliability considering the causality relationship of performance shaping factors (PSFs) in this paper, a fuzzy logic and analytic hierarchy process (AHP)-based method is established to more objectively assess SA reliability. The weight of PSFs is identified using AHP, and a fuzzy logic method is used to simulate the fuzzy assessment and reasoning process of operator's SA reliability, and a standardized method is built to determine the fuzzy rule base of fuzzy reasoning system for SA reliability assessment for reducing the subjectivity and uncertainty of expert judgment. Finally, an example is provided to illustrate the specific application of the proposed method. The results show that the established method takes account of the weight of PSFs and their causal influencing relationship, and the fuzzy logic method used to assess SA reliability can overcome the subjectivity and uncertainty of expert judgment, which makes the assessment results more objective and realistic. Furthermore, the method can be used to get more SA error data and have a wide range of application value.
