單階平行機群之精實排程系統

本研究針對單階平行機群建構精實排程系統，主要應用「精實生產」及「群組技術」之概念，將排程系統分三大階段，著重於排程之邏輯與步驟的導入。第一階段為導引（Lead）階段，藉由拉式生產與批量生產之概念掌握訂單資訊，並應用群組技術使機台與訂單群組化。第二階段為決策（Selection）階段，運用後推排程方法同步結合平行生產、標準化及機台產能平均化，提出排單法則。第三階段為回饋（Signal）階段，藉由看板系統與目視管理輔助現場生產，並利用差異分析尋找造成差異原因。而在個案驗證方面，本研究以境外某印刷廠為驗證對象，實際導入模式，其成效具體反映至日平均產量、生產排程達成率兩方面，日平均產量於改善後有效提升為改善前之70%；而生產與排程達成率，改善後之達成率較改善前增加至60%，由此可知，本研究模式「單階平行機群之精實排程系統」在實務中確實有可行性與有效性，因此對於其它類似型態之製造業亦有所幫助。

This research applies the group technology and lean production system to scheduling system based on the one-stage parallel machine group. The model is named as “Lean Scheduling System for One Stage Parallel Machine Group; LSS”, which divides the scheduling system into three stages. The first is lead, it masters the order information on the basis of pull system and batch process, and also groups the machines and orders through group technology; the second is selection, it offers the dispatching rules by means of parallel production, standardization, and the loading of machine capacity leveling; and the last is signal, it assists the production by kanban system and visual management, and finding the causes induced the variation by gap analysis. Furthermore, after executing the model in an overseas printing plant, it enhances the daily average output about 70%, and increases the achievement percentage of scheduling around 60%. Overall, the LSS model has its effects for the similar manufacturing.
