摘　　要：以多功能全回转起重船为研究对象,针对起重机起吊重物并做大角度回转作业工况,建立多目标优化数学模型,以各个压载舱调载量最大值最小、起重机起吊重物回转过程中船舶纵倾角最小和横倾角最小作为三个优化目标,利用多目标遗传算法,求解获得配载方案最优集,同时利用基于熵权的TOPSIS(Technique for Order Preference by Similarity to an Ideal Solution)方法,客观准确地得到压载调拨与吊机作业配合的最终配载方案。结果表明利用AQWA(Advanced Quantitative Wave Analysis)静水力分析可较为准确地获得船舶重心与倾角的关系,且多目标优化方法可输出多个最优配载方案,多准则决策方法可结合工程经验和客观性输出最终配载方案,该优化决策方法可高效得到简单有效的起重船配载方案,为工程中的压载优化提供参考。A multi-objective optimization mathematical model is established for revolving crane vessel with multi-functions and under the conditions of the crane lifting load and doing large-angle rotation operation.By taking the minimization of the maximal allocation value of each ballast tank and the minimization of both the trim and the heel angles of the vessel during the crane lifting and revolving as three optimization objectives,an optimal set of ballast allocation schemes is worked out by using the multi-objective genetic algorithm,and then the final scheme for the coordination of ballast allocation and crane operation is objectively and accurately obtained by using TOPSIS(Technique for Order Preference by Similarity to an Ideal Solution)method which is based on entropy weight.The results show that the relationship between the gravity center and the inclination of the crane vessel can be accurately obtained through hydrostatic analysis using the AQWA(Advanced Quantitative Wave Analysis)method and several optimal ballast allocation schemes can be output by the multi-objective optimization method.The final ballast allocation scheme can be output by using multi-criteria decision-making method and combining engineering experience and objectivity.By using the above method,a simple and effective ballast allocation scheme can be obtained,thus providing references for the optimization of ballast scheme in the project.
