摘要
船舶的结构设计过程需要分析和处理大量的不确定性因素,比如结构尺寸、载荷、强度和配合公差等参数,是一个典型的多目标优化过程。为了提高船舶结构的质量,对大量不确定性因素进行优化求解具有重要的意义。本文根据船舶结构设计过程的不确定因素,建立多目标模糊优化函数模型,并采用多目标分层序列法和权重分配法对具有重要性差异层次的目标函数进行判定,找到船舶结构设计参数的最优解。
In the process of ship structure design, it is necessary to analyze and deal with a large number of uncertain factors, such as structural dimensions, load, strength and fit tolerance, which is a typical multi-objective optimization process.In order to improve the quality of ship structure, it is of great significance to solve the uncertain factors. According to the uncertain factors of ship structure design process, a multi-objective fuzzy optimization function model, and the multi-objective hierarchical sequence method and weight distribution method of objective function for different levels of importance to determine optimal ship structure design parameter of solutions.
