Authors summarized the knowledge and reasoning way of navigator about navigational conditions. Then two types of expert systems for evaluating nautical environments were produced as a trial.As the first step, a hierarchy structure of such factors as relating navigational environments was made. They were weighted by Analytic Hierarchy Process to assess the risk of navigation. Marine traffic survey system and a ship handling simulator were also investigated as means for finding the behavior and knowledge of navigators.An expert system supporting the navigation through congested waters at night was mainly studied because it will to be useful for practical use in future. Then experimental studies on how navigators recognize nautical marks and fix own ships position in a route were carried out by a nocturnal ship handling simulator. The ship's tracks avoiding obstacles on a route were also oberved at a congested water by a radar.Through these studies some of the nautical knowledge and reasoning way of navigator at congested waters were summarized. The two types of the expert systems were produced based on these results. One is for avoiding obstacles on the route. The other is for evasive the collision between ships. Fuzziness at the judgments were taken into acconut for the both system. The validities of them were also examined.

作者总结了航海家对于航行条件的认识和推理方式。然后试制了两种类型的航海环境评价专家系统。第一步，建立了航海环境相关因素的层次结构。通过层次分析法对它们进行加权，以评估航行风险。还对海上交通调查系统和船舶操纵模拟器进行了研究，作为了解导航员行为和知识的手段。主要研究了支持夜间通过拥挤水域导航的专家系统，因为它将在未来的实际应用中发挥作用。然后通过夜间船舶操纵模拟器对导航员如何识别航海标记并确定本船在航线上的位置进行了实验研究。通过雷达观测船舶在拥堵水域避障的航迹。通过这些研究总结了拥堵水域航海人员的一些航海知识和推理方式。两种类型的专家系统都是根据这些结果产生的。一是为了避开路线上的障碍物。另一个是为了规避船舶之间的碰撞。两个系统都考虑了判断的模糊性。还检查了它们的有效性。
