| Research Abstract |
The vessel operation space was regarded as the complexity system, and the mutual interference type operation environmental expression model which can express the interaction of the object group which constitutes that environmental place was developed. The marine traffic flow simulation system which implemented the operation environmental expression model and the ship agent group that can carry out emergence of the vessel group action was constructed. The ship cluster behavior model was adopted as the decision making function of a ship agent, and the model has been improved to it Furthermore, the sensing function has been improved and the calculation load was reduced. The constructed simulation system is suitable for the marine traffic environmental assessment, a port design, etc. The main research track records are shown below.
1. The criterion of judgment of a ship operator and the survey of ship operation were performed, and the emergence of group action, unification and separation from a group of a group, collision avoidance with a vessel and collision avoidance with a static obstacle, the mute navigation characteristic, etc. were investigated.
2. The simulation model was improved and the simulation of the Tokyo Bay marine traffic flow near a Uraga Suido Traffic Route and evaluation of the marine traffic flow were performed.
3. The property emergence of group behavior in case the ship which performs non-cooperative action to the surrounding ship exists, and the possibility of spy ship search was discussed.
4. Functional enhancement of the ship agent was performed and improvement in the expression ability of a traffic flow and load mitigation of simulation computation was performed.
5. The marine traffic flow simulation system was released on the Internet, and the international joint research environment using a web browser was improved
