摘　　要：介绍了船舶结构理性设计方法的理念、特点和意义,解释了它与传统的单纯依赖于设计者的经验或规范的设计方法的区别与优势。针对理性设计方法的基于计算机辅助计算和优化策略与算法的特点介绍该设计方法在应用中存在的问题,包括计算成本较大以及参数化建模困难等。并针对这些问题对国内外开展的相关研究及其进展进行了总结。最后,展望了船舶结构理性设计方法在船舶设计领域的应用前景。In this paper,the concept,characteristic and significance of the rational-based design method in ship structural designs were introduced.Firstly,the differences between the conventional rule-based（or experience-based）design method and the one presented here were described.Next,with the consider ation that the rational-based design method is both computer-based and optimization-based,its defects and limitations in practical applications were introduced,i.e.high costs in computation and difficulties in parametric modeling.Finally,some domestic and foreign research works related to these limitations were summarized and discussed in detail,and some application prospects of this method in ship structural de signs were proposed.
