避航エキスパートシステムと航路航行シミュレーションに関する研究

抄録

In the present report an expert system for ship collision avoidance is developed. The expert system has a knowledge base of hierarchical structure. The knowledge base consists of many rule modules and the rule modules are classified into several levels. Combining with the knowledge base with the subsystems for the data acquisition on traffic situations and for the guidance controls of ship position, the developed system can lead a ship safely to her destination even under heavy traffic conditions. If ships on traffic lanes are conducted by the collision avoidance expert system, marine traffic simulations can be carried out as an application of the expert system. Examples of such simulations show successfully that the system has an excellent ability of collision avoidance and also that the traffic simulation thus obtained is the powerful tool for investigations on marine traffic problems.
