MATHEMATICAL OPTIMIZATION METHODS APPLIED TO SHIP DESIGN

摘要

Various existing mathematical methods of functional optimization and optimization criteria were examined for application to the ship design problem. Based on this study, the Exponential Random Search technique in conjunction with "Multiple Parameter Weighting Criteria' were used in a sample design study of a cargo ship. Results of this study show that this approach to the ship design problem:n(1) yields better results than any other method available at the present time;n(2) arrives at a solution in less time than current methods;n(3) is more versatile than any other method available;n(4) performs the optimization more correctly because it does not neglect any of the features of the problem of optimizing a function of several variables. The demonstrated flexibility, versatility, and efficiency of the chosen method constitute in the author's opinion, a powerful tool in the preliminary design of ships.
