Abstract

The environment adaptability especially integrated sailing performance in rough sea of ships is very important. In this paper the evaluation index system and method of wind and wave environment adaptability were proposed. Then the relative importance of the given indices was analyzed, and the weighting coefficients of the indices were given by estimation matrixes. Besides this the evaluation equation was built. And the AHP method and the method based on fuzzy theory were used for evaluating the environment adaptability of a hybrid monohull and a round bilge monohull. Furthermore, the effect of different models and weighting coefficients given by different matrixes for evaluation results were analyzed. The research indicated that the choice of evaluating parameters had great influence on the evaluation results, and the weighting coefficients were the difficult point but critical point for environment adaptability evaluation of ships.
