Fuzzy Analysis of Multi-criterion Orthogonal Optimum Design of Ship's Main Dimensions

本文根据正交代化设计及模糊综合评判原理结合船舶主要参数优化设计的特点，提出了船舶主要参数的多目标正交代化设计的模糊分析方法。此方法解决了以往在船舶主要参数优化设计中存在的显著性检验中跨水平问题，同时节省了大量的统计计算和方差分析的工作量。给出的应用实例的计算结果表明，本文提出的分析方法计算简便、实用而又准确可靠，并易于被设计人员掌握。

Based on the orthogonal optimum design and fuzzy comprehensive evaluation, a method for fuzzy analysis of multi-criterion orthogonal optimum design of ship's main dimensions is presented. The method solved the problem of different levels in significance verificafion in multi-criterion orthogonal optimum design, i.e. one factor may cause different effect-level for different indexes. In addition, lots of calculation work for statictica1 calculation and variance analysis may be avoided. Application examples show that the proposed method is simple and accurate, and easy to use by ship designers.
