| 摘 要： | 大型船舶船体分段装配的安排是现代化船厂面临的一个重要问题.首先对分段装配过程所涉及的工艺约束、分段制造车间生产能力以及分段储备量进行分析,建立在给定船坞周期条件下实现分段储备成本最小的目标函数;然后提出一种适合此类问题的改进遗传算法(Modified Genetic Algorithm,MGA)来求解装配顺序,从而获得全局最优解或者次优解.通过合理安排每个总段(或分段)的装配顺序实现对分段需求量的控制,从而达到最低的建造成本消耗.以实际的某大型船舶74500DWT散货船为例阐述改进遗传算法求解船体装配顺序的方法,所得结果与传统经验方法的结果进行了比较和分析.

| Abstract: | Block Erection in Shipyard is a complex process.A method based on modified genetic algorithm for optimization of block erection process is proposed.Firstly,the constraints of erection network and the production ability of block are analyzed and the objective function to minimize the cost of block inventory is given.Then,a modified genetic algorithm is used to optimize this problem,and the coding approach and a crossover operator are introduced in details.Finally,a case study of the optimization of erection process of a 74500 DWT bulk carrier is given and the result shows that this optimization method is effective. |
