Abstract: A production schedule model based on genetic algorithm for copper sheet and strip with weighted coefficient is built,the model considers of the characteristic of production process and multi-objective of production schedule about copper sheet and strip.Then genetic algorithm is used to schedule the model,and a near optimized result is got.In the algorithm,the paper uses methods such as matrix coding,hybrid selecting and three-individual-crossover.Each operator of the algorithm has been designed to find the best alternative which can meet the constraint condition in finite calculation steps.The results of simulation show that this algorithm can solve scheduling problem of copper sheet and strip effectively and have better practicality.

Key words: copper sheet and strip, production scheduling, modeling, genetic algorithm

摘要: 根据铜板带生产流程的特点,考虑到铜板带生产调度的多目标性,建立基于遗传算法带加权系数的铜板带生产调度模型;然后应用遗传算法对该模型进行调度并获取近似最优解。该算法采用矩阵编码、混合选择策略和三个体交叉方法,使其在有限的步骤内,找出所有满足约束条件的最优或次优解。仿真结果表明该算法可以有效地解决铜板带生产调度问题,具有实用性。
