本文从约束理论(TOC)出发,在识别出生产系统瓶颈的基础上,提出了以瓶颈工序生产提前期最小化的生产批量的生产控制方式,并采用数学模型定量方法分析和确定了在瓶颈环节产品切换的加工批量和传输批量。通常,在非瓶颈工序上常用较小的加工批量,但是在瓶颈资源上则常把较小的传输批量组合成较大的加工批量,以最大限度利用瓶颈资源,提高其有效生产能力。这样可以减少工件在工序间的等待时间,减少在制品积压,保持生产过程物流的同步化。
Based on the constraint theory (TOC), based on identifying the bottleneck of the production system, this paper puts forward a production control method that minimizes the production lead time in the bottleneck process, and uses the mathematical model quantitative method to analyze and determine the bottleneck link Product switching processing batch and transmission batch. Often, smaller processing batches are often used on non-bottleneck processes, but smaller transmission batches are often combined into larger processing batches on bottleneck resources to maximize the bottleneck resources and increase their effective production capacity. This can reduce the workpiece waiting time between processes, reducing the backlog of products, to maintain the synchronization of the production process logistics.
