摘要
将限界搜索模糊优化与混沌算法复合构成限界搜索模糊混沌算法,并将其应用于大中型船舶性能或结构特性综合优化计算分析中。建立了以加权和形式为目标函数的综合优化数学模型,编制了计算软件,进行了大量对比计算。计算结果表明:这些优化方法和计算软件界面友好、可靠性和计算效率高,并且具有较高的实用性,运用于大中型船舶性能或结构特性综合优化是切实可行的;对于大中型船舶方案或初步设计也有使用价值。
In this paper,the fuzzy-chaos algorithm is proposed,which is composed of the fuzzy genetic algorithm of bound search and the chaos algorithm.This algorithm is applied to optimize,calculate and analyze large-scale ship performance or structural characteristics.Establishing the integrate optimization mathematical model which form is the linear addition power average sum of all object functions,programming the calculation software and carrying on a lot of comparison calculation. The calculation results show that these optimization methods and the calculation software have friendly interface,good dependability and higher calculation efficiency; this optimization method and the calculation software have practicability and applied to integrally optimize the ship performance or structural characteristics is feasible.To large-scale ship project or their primary design it is worth using.
