船舶结构优化设计的研究进展

Development of Optimization Investigation in Ship Structural Design

阐述工程结构优化若干前沿领域，即形状优化、模糊优化和遗传优化的基本原理和特点，以及它们在船舶结构设计中的应用．形状优化把数学规划论与边界元分析相结合，模糊优化把数学规划论与模糊集合论相结合，遗传优化把数学规划论与生物进化论相结合．这些多学科交叉有力地促进了结构优化设计深入发展，取得了良好的成果．

This paper introduces the basic principles and features for some advanced fields of structural optimization in engineering and their applications to ship structural design, including shape optimization, fuzzy optimization and genetic optimization which combine mathematical programming theory with boundary element analysis, fuzzy set theory and biology evolution theory respectively. These intersections of multidiscipline bring about a great advance in optimum design of structures.
