舰船主尺度论证中的多目标综合评估

Multi-Objective Synthesized Evaluation in Principal Dimensions Design of Ship

舰船主尺度是舰船总体设计中最重要的问题之一,直接影响舰综合航行性能的优劣。为寻求性能综合较优,避免单一性能最优的局面,提出一种多目标综合评估模型,并将其应用于某舰主尺度论证中,首先以满足布置、重量等因素为前提提出多种主尺度方案,再以舰的稳性、快速性、耐波性为目标,根据设计需求分别构造目标函数以及将多目标问题转化为单目标问题的决策函数,通过分析评估优选出3种性能综合较优的方案,使得优化结果更合理有效。

The principal dimensions are one of the most critical problems in the ship design and will bring direct effects on the comprehensive performance of ship.To avoid single performance optimization,a multi-objective synthesized evaluation model was presented and introduced in the principal dimensions design of a warship in this paper.Several schemes were provided in the condition of matching the arrangement,weight and some related elements.An optimized result was obtained by synthetically evaluating the target functions in regards to stability,speed and sea keeping of each scheme,then made the optimization result more reasonable and effective.
