摘要

本文讨论了印刷电路板(PCB)组装过程中出现的优化问题。今天的自动化制造系统涉及到各种各样的特殊用途机器人,它们共同构成了生产线。生产组织包括几个需要解决的问题,从调度的顶层战术决策,到产品分组和生产线平衡,再到单机优化问题。本文讨论了单机优化问题:确定零件插入顺序,并安排不同喷嘴(工具)在打印头上的分配。目的是使这台机器的产量最大化。考虑的机器类型是通用表面安装(GSM)机器。通过对生产情况和机器进行建模,将出现的优化问题分解为层次,并开发有效的启发式求解方法来解决问题。实际应用结果表明,与现有的优化系统相比,新优化系统的生产率显著提高(5-10%)。

ON SOLVING SINGLE MACHINE OPTIMIZATION PROBLEMS IN ELECTRONICS ASSEMBLY
This paper deals with optimization problems arising in printed circuit board (PCB) assembly. Today's automated manufacturing systems involve a large variety of special purpose robots that together form the production line. The organization of the production includes several problems to be solved, starting from top-level tactical decisions at scheduling, through product grouping and line balancing, to single machine optimization problems. The paper deals on the single machine optimization: determining the order of component insertions and scheduling the assignment of different nozzles (tools) to the printing heads. The aim is to maximize the throughput of the machine. The machine type considered is the general surface mounting (GSM) machine. The problem is solved by modeling the production situation and the machine, decomposing the arising optimization problems into hierarchical levels, and developing effective heuristics for solving them. The practical results of the new optimizing system show significant increase (5–10%) in the productivity when compared to the current state.
