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.

作者总结了导航器关于导航条件的知识和推理方式。然后，将两种用于评估航海环境的专家系统作为试验。作为第一步，建立了相关导航环境等因素的层次结构。他们通过分析层次结构过程来评估导航风险。还对海洋交通调查系统和船舶处理模拟器进行了研究，作为找到导航器的行为和知识的手段。一个专家系统在夜间通过拥挤的水域进行了支持，主要研究了通过拥挤的水域进行导航，因为它将在将来对实际使用非常有用。然后，关于导航器如何识别航海标记和修复自己在路线中的船只位置的实验研究是由夜间船舶处理模拟器进行的。该船的轨道避免了路线上的障碍物，还通过雷达在拥挤的水上渗出。通过这些研究，总结了这些研究的一些航海知识和推理方式。专家系统的两种类型是根据这些结果生产的。一种是为了避免路线上的障碍。另一个是为了逃避船只之间的碰撞。判断的模糊性被认为是两个系统的辅助。还检查了它们的有效性。
