内河成品油船结构优化设计

Structural design optimization of a river product-oil tanker

将2 000 t内河成品油船货油舱结构设计过程表达为两阶段两个分支的动态规划问题,并且用动态规划方法进行优化设计,实例表明,动态规划方法能有效处理离散设计变量优化问题,为中小型船舶设计提供一个逻辑框架,设计者只要按照动态规划原理,按部就班地分别设计各构件,就能得到结构优化设计方案。

This paper describes that structural design optimization of a 2 000 DWT river product-oil tanker as a sequential divergent branched system and optimize it by dynamitic programming （DP）. The example shows that DP is well suited to the discrete-variable optimization and provides a logical framework for the structure design of small and mid-sized ships so that a designer can find the optimum structure design by systematic decision- making.
