Applying the existing domain model in ship domain research in a restricted area can be difficult owing to multiple factors that must be considered. This study presents a new domain model that can be applied in such environments. According to Endsley's theory of situation awareness, people have their own criteria in decision making based on factors such as individual and environmental factors. To investigate these factors, 125 seafarers were interviewed and threshold values based on their awareness were examined. The factors were evaluated as the closest points of approach. Domain modelling was performed based on these seafarer awareness values; then, the existing and awareness domains were compared, revealing that the awareness-based domain of seafarers is more affected by ship manoeuvrability than by ship size and speed, unlike the findings of existing domain research. Therefore, this study presents a new domain model that is both realistic and practical in a confined area, including various factors considered by seafarers based on the awareness values formed.

海员在限制区域内基于意识的领域建模

由于必须考虑多种因素，在受限区域的船舶领域研究中应用现有领域模型可能很困难。本研究提出了一种可以在此类环境中应用的新领域模型。根据恩兹利的情境意识理论，人们在基于个人和环境因素等因素的决策中都有自己的标准。为了调查这些因素，我们采访了 125 名海员，并检查了基于他们的意识的阈值。这些因素被评估为最接近的点。基于这些海员意识值进行领域建模；然后，将现有域和意识域进行比较，发现海员的基于意识域受船舶操纵性的影响比受船舶大小和速度的影响更大，与现有领域研究的结果不同。因此，本研究提出了一种新的域模型，该模型在受限区域中既现实又实用，包括海员根据形成的意识值考虑的各种因素。
