摘要
针对优化船舶操纵收敛效果不佳问题,引入多目标进化计算法优化船舶性能设计.基于多目标船舶操纵进化计算法,构建以船舶旋回直径和直线航行能力为评估指标的优化模型,采用基本不可行解差分算子,建立多目标优化计算法架构;选取优化基本不可行解,制定新的选择标准.与MOEA/D算法、加权算法和pareto算法比较分析结果表明,本研究算法可为船舶研究和设计人员提供更多优化船舶操纵设计策略的结果,从根本上提升了设计策略的收敛效能.
Abstract
In order to solve the problem that the convergence effect of optimizing ship maneuvering is not high,a multi-objective evolutionary algorithm is introduced to optimize ship performance design.In this study,a multi-objective evolutionary calculation method for ship maneuvering is proposed,and the optimization model of ship cycle diameter and straight-line navigation ability is constructed,and the basic infeasible solution difference operator is used to establish the framework of multi-objective optimization calculation method.Secondly,the basic infeasible solution of optimization is selected to develop new selection criteria.Compared with MOEA/D algorithm,weighted algorithm and pareto algorithm,the results of this study show that it can provide more results for ship researchers and designers to optimize the ship maneuvering design strategy,and fundamentally improve the convergence efficiency of the design strategy.
