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.
