摘要： Cycle time and throughput of a manufacturing facility is effectively manages by a control system that employs a combination of a long-term horizon model and at least one short-term horizon model to generate control signals for a set of machines in a manufacturing facility. The long-term horizon model determines long-term average time allocation percentage for each machine for a given set of throughput targets and cycle time targets for products to be manufactured. Each of the at least one short-term horizon model determines queues for immediate use at processing tools, while the queues are subjected to a secondary adjustment based on the time allocation constraints generated by the long-term horizon model. The combination of the long-term and the at least one short-term horizon models provides a stable long-term proactive WIP bubble-management as well as short-term WIP bubble management.
摘要翻译： 制造设施的循环时间和生产量由采用长期水平模型和至少一个短期水平模型的组合的控制系统有效地管理，以生产制造设备中的一组机器的控制信号。 长期视野模型确定了要制造的产品的给定集合吞吐量目标和周期时间目标的每台机器的长期平均时间分配百分比。 所述至少一个短期水平模型中的每一个确定在处理工具上立即使用的队列，同时基于由长期视野模型产生的时间分配约束对队列进行二次调整。 长期和至少一个短期视野模型的结合提供了稳定的长期主动的WIP泡沫管理以及短期的WIP泡沫管理。
