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.

总结了航海人员对航行条件的认识和推理方式。在此基础上，初步建立了两种航海环境评价专家系统，并对影响航海环境的因素进行了层次结构分析。运用层次分析法对各指标进行加权，对航行风险进行评价。研究了海上交通调查系统和船舶操纵模拟器作为发现驾驶员行为和知识的手段，重点研究了支持夜间通过拥挤沃茨的导航专家系统，以便将来在实际中使用。然后利用夜间船舶操纵模拟器对航海员如何识别航海标记并确定自己船舶在航线上的位置进行了实验研究。通过雷达观测船舶在拥挤水域的避障航迹，总结了船舶在拥挤沃茨的一些航海知识和推理方法。在此基础上，研制了两种类型的专家系统。一个是避开路上的障碍物。另一种是用于规避船舶之间的碰撞。在判决中，两种制度都得到了一致的认可。并对它们的有效性进行了检验。
