Research on Ship Cabin Layout Optimization Combining Modular Thinking and PGA Algorithm
-
摘要: 船舶住舱环境对船员的心理状态及工作效率有着显著的影响，针对住舱的布局优化是能够提升舰队整体作战水平的重要方式之一。本文主要针对住舱空间的布局优化，提出模块化思维的划分方式，并利用模糊聚类分析将住舱模块进行划分，利用PGA算法进行多目标优化计算，从而引导遗传算法的演化结果更符合其工程实用性，来有效提升船员居住的舒适度，进一步提升海上长航工作的质量。最终通过重心排序的模糊综合评价对输出的优化方案进行验证。Abstract: The living cabin environment of a ship has a significant impact on the psychological state and work efficiency of the crew, and optimizing the layout of the cabin is one of the important ways to improve the overall combat level of the fleet. This study mainly focuses on the layout optimization of the living cabin space inside ship, proposes the division method of modular thinking, and uses fuzzy cluster analysis to divide the cabin module, and uses the PGA algorithm to perform multi-objective optimization calculation, so as to guide the evolution results of the genetic algorithm to be more in line with its engineering practicability, so as to effectively improve the comfort of crew living and further improve the quality of long-distance navigation work at sea. Finally, the fuzzy comprehensive evaluation of center of gravity ordering verifies the optimization output scheme of living cabin.
