Comprehensive Evaluation of Ship ManeuverabilityBased on the Algorithm of Deviation Maximization

This paper applied the algorithm of deviation maximization to the comprehensive evaluation of ship maneuverability. By introducing the weighting vectors and normalized decision making matrix as well as their corresponding effects on the evaluation process，the comprehensive evaluation system of ship maneuverability was established，with the specific principle and calculation procedure of this method illustrated. To test the algorithm，two ship models were evaluated for various maneuverability parameters. The results show that the method of maximizing deviations is maturity in theory as well as precisely and reliably in practice.
