Information in ship handling is crucial. However, a quantitative evaluation of the role of information value is never been undertaken, no technique established. In the present study, we proposed a technique for evaluating an information value, and we aimed at destination of another ship in all of information. Information of destination has influence on decisions of ship handling. The decisions of ship handling were modeled by the decision tree theory. The method for finding the information value was devised and by introducing information value theory. Experiments using a ship handling simulator, to verify this technique, were undertaken. The condition of difference of presence of information was given to the subjects. At the experiment, subjects were divided into two groups. The ES-model was applied to the experiment. Ship handling process was evaluated. The result value of the experiment was lower the group of given information than the group of not given it. The expected value was calculated by using the result value. The information value was expressed by using the expected value and the value of the group of given information, to produce the result of the experiment, and decision tree theory.
