【摘要】：船舶电缆路径布置的设计是船舶生产设计中一项非常重要的工作,但是目前,船舶电缆路径的设计主要由人工凭借丰富的经验来完成,这样不仅效率低下,而且费时又费力,这严重制约了船舶电气设计的效率。如果能找到一种新方法解决这一项工作,就能够节省大量的时间和费用,大大加快船舶电气生产设计的进程。正是基于上述实际工程中存在的问题,本文提出了一种新的解决方法来实现船舶电缆的优化布置。 本文在遗传算法的基础上,与实际工程中电缆铺设存在的问题相结合,通过改进遗传算法中的一些缺点,研究出了一种符合电缆优化布置的新方法。这种新方法包含以下4部分：①在电缆路径布局中进行编码设计；②电缆路径种群的初始化；③按照实际情况设计目标函数和适应度函数；④改进相关的遗传算子。之后通过实验的仿真数据,证明了新方法的提出对船舶电缆的优化布置是有效的,能够解决遗传算法中的一些缺陷并得到较为理想的结论。 最后,根据以上的新方法,开发出一款简单实用的电缆布置软件,并且通过实例证明此软件能够在船舶电缆的布置中起到省时省力的效果,而且生成的结果也能满足工程需要。
[Abstract]:The design of ship cable routing is a very important work in the ship production design, but at present, the design of ship cable routing is mainly accomplished by manpower with rich experience, which is not only inefficient, but also time-consuming and laborious. This seriously restricts the efficiency of ship electrical design. If a new method can be found to solve this task, it will save a lot of time and cost and speed up the process of ship electrical production design. Based on the problems in practical engineering, this paper presents a new method to realize the optimal arrangement of ship cables. On the basis of genetic algorithm, this paper combines with the problems existing in cable laying in practical engineering, and through improving some shortcomings of genetic algorithm, a new method which accords with the optimal arrangement of cables is developed. The new method consists of the following four parts: (1) coding design in cable path layout; (2) initialization of cable path population; (3) design of objective function and fitness function according to actual conditions; (4) improved genetic operator. Through the simulation data of the experiment, it is proved that the proposed new method is effective for the optimal arrangement of ship cables, and can solve some defects in genetic algorithm and obtain a more ideal conclusion. Finally, according to the above new method, a simple and practical cable arrangement software is developed, and it is proved by an example that the software can save time and effort in the arrangement of ship cable, and the result can also meet the need of engineering.
