Abstract

Abstract: A hybrid genetic algorithm to solve the rectangular strip packing problem is proposed.Considering some special constraints and simplifying the cutting process，the idea of three-stage is adopted to design the improved algorithm.The genetic operation is improved and an adjustment operation is used to optimize the cutting plan after the mutation operation.In initial population construction some simple methods are used to make the results converge more quickly.The experiment results indicate the validity of the presented algorithm.

摘要： 采用混合遗传算法求解矩形件带排样问题，采用三阶段排样方式以满足特定的约束或简化切割工艺。改进遗传算子，在变异操作之后使用调整操作，以进一步简化得到的排样方案。在初始种群构造时，根据矩形件的特性采用一些简单有效的方法，使结果更好更快地收敛。实验结果表明方法对解决这类问题是有效的。
