| Research Abstract |
The research in the past two fiscal years was aiming at automatic navigation system, for sips in narrow and congested waterways, but it has covered wide technology areas. It will be summarized as follow.
(1) The mathematica model of ship manoeuvrability for narrow waterway navigation was investigated conducting towing tank experiments.
(2) Free sailing model experiments were conducted for the purpose of validating the mathematical model of ship manoeuvrability at low advanced speed.
(3) Measuring system of the positon and the motion of a model ship has been developed. The system was based on image analysis technique.
(4) Feasibility study on automatic berthing system using tug boats was started. It is confirmed that neural network my be applicable for this purpose.
(5) Final research conclusion was summarized in a simulation system. Automatic navigation system using knowledged-bse expert system, fuzzy logics and/or neural network was widely investigated and confirmed to work well through the simulation study.
