摘要
为了满足市场需求,多品种、变批量逐渐成为模块化批量装配生产企业的生产特点。通过分析模块化批量装配的生产流程和生产特点,以装配生产周期最短化为目标,考虑装配工艺约束,采用等量分批策略,建立模块化批量装配生产调度模型。基于模型分析,采用改进双层遗传算法对模型进行求解,解决企业因多品种、变批量而引起的产品装配生产周期长的问题。以中小型液压注塑机的装配生产为例,建立生产仿真模型,验证调度模型的正确性。
In order to meet with the market demand,multi-variety and ariable batch have gradually become the production characteristics of modular batch assembly production enterprise.By analyzing the production process and production characteristics of modular batch assembly,aiming at shortening the assembly production cycle,considering the assembly process constraint,and adopting the equal batch strategy,the modular batch assembly production scheduling model was established.Based on the model analysis,the improved bi-level genetic algorithm was used to solve the problem of long product assembly and production cycle caused by multi-variety and variable batch.Taking the assembly and production of small and medium-sized hydraulic injection molding machine as an example,a production simulation model was established to verify the correctness of the scheduling model.
