文中分别阐述了目前应用较为普遍的MDF及IDF系统重构方法的基本原理，以46000t油船主尺度及型线的优化设计为例，采用两类不同的系统重构方法进行了优化．结果表明，IDF方法是船型多学科设计优化系统重构的理想方法．

英文摘要：

Ship hull form hydrodynamic performance integrated optimization usually requires a mass of calculation to complete a feasibility design, and the huge calculation complexity means that it is diffi- cult to make a effective optimization design, must carries on system reconstruction. The paper sepa- rately illustrates the basic principle of MDF and IDF system reconstruction methods which are univer- sally used at present, takes 46000t oil tanker principal dimension and hull form optimization design as example using two kinds of system reconstruction methods. The result presents that IDF is a ideal method of hull form multidisciplinary design optimization system reconstruction. The research makes a foundation for hull form multidisciplinary design optimization platform into application.
