摘要
针对柔性生产线可适应多品种、中等批量产品需求的特点,提出一种面向零件族的柔性生产线构形设计方法。以投资最少、生产线空闲时间最短和生产线上的加工任务重现度最大为优化目标,综合考虑空间约束、节拍约束和加工任务先后顺序约束,建立柔性生产线构形设计的多目标线性混合整数规划模型;根据该模型的特点,给出基于分支定界的优化算法,求得模型的最优解。以缸盖柔性生产线为实例,验证该设计模型和优化算法的有效性。
Aiming at the characteristics of flexible manufacturing line（FML） that it can supply the demand for multi-specification and medium-batch products, a configuration design method of FML orienting part family is proposed. Multi-objective linear mixed integer programming model of configuration design of FML is established by taking least investment, shortest idle time and largest task recurrences as the optimization objective, and considering constraints of space, cycle time and task sequence. According to the characteristics of the model, an optimal algorithm based on branch and bound is provided to obtain the optimal solution of the model. The effectiveness of this design model and optimal algorithm is verified by the FML with the part family of cylinder head.
