面臨全球供應鏈體系的競爭，有競爭力的企業不僅需具備產品、品質及價格等傳統競爭要素外,快速之交貨週期(Lead time)與服務水準(Service level)亦日益受到重視。
一般研究對於交期控制(Lead Time)及服務水準(Service level),皆著重於整體生產週期縮短(Cycle Time Reduction)或看板管理,但面對多機台流線式製程之產出管理,則鮮少討論。
本研究係利用計劃評核術(PERT)*控制節點(nodes)的其中之法則-最晚完成時間(LF),配合D.D.(Due Date)派工法則,針對瓶頸或關鍵站別,對不同之生產批次(Production Lot)予以進行生產時程進度之控制並準時入庫,以期達到快速之交貨週期(Lead time)與服務水準(Service level)之目的。因此透過本研究之探討及個案實施之驗證,可針對多機台流線式製程提供具體且有效之產出管理模式,以利其相關產業在面臨全球供應鏈體系的激烈競爭下，建立快速之交貨週期(Lead time)與高服務水準(Service level)之核心競爭力。

Modern manufacturing firms compete not only on the traditional basis of product quality and price, but also increasingly on the basis of lead time and service level, which are both affected by cycle time.
General research, for handing in a issue of lead time control and service level, all focus on cycle time reduction or Kanban, the bill-board is managed. But there is a little study on the throughput control for “Floor Shop with Multiple processors”.
This paper provides the mechanism which access the PERT skill of L.F. (latest finish) and dispatching rule of EDD (earliest due date) to control the throughput at some critical or key stages for each production lot to ensure the fulfillment of delivery lead time & service level.
