Using Fuzzy Cognitive Maps to Analyze the Information Processing Model of Situation Awareness

Situation Awareness (SA) is a vital factor in man-machine systems. In the classic information processing model of SA, the elements within human cognition, system properties and SA-judgement itself effect with each other, which makes the SA a complicated system. In order to research SA in a comprehensive way, the approach of Fuzzy Cognitive Maps(FCM) is used to remodel and analyze it. Through standard interviews, related concepts are found and the SA-FCM model is structured. An adjacent matrix is created by exploring the inference mechanism of concepts and their casual relations in the graph model. Several properties of the SA system can be dug with matrix theories. And how to achieve an expected SA performance by changing the factor of HCI design is discussed. The methodology and further results of this paper will benefit the related areas in human-machine systems, especially HCI design, operators training and automation level set-up.
