  3. 現狀圖

  4. 計劃趕不上變化 預測有偏差 不良或整修 事務管理的錯誤 設備故障 出勤狀況的變化 作業員能力的差異 生產計劃(MRP)大都缺乏回饋機制

  5. WIP inventory http://www.fabricatingandmetalworking.com/2013/09/your-mother-doesnt-work-here-why-housekeeping-matters/

  6. 大量生產方式 • 對各工程『個別』指示生產計劃 (MRP) • 前後工程各自獨立生產 • 發生欠料、瓶頸作業時 • 不需要或不急用的零件,堆積如山 • 下游作業,亦產生零組件堆積的現象 • 前製程無法提供足夠的成品 • 但是、其它零組件『已準時』配送到現場

  7. 解決之道 • Flow (暢流) • 福特汽車的連續式生產線 • Pull (拉式生產) • Just in Time • 看板管理

  8. 準則2: 在能流動的地方,都讓其連續流動 Flow

  9. Cell for manufacturing • http://www.youtube.com/watch?list=PL3DBF8F02CA89C98C&v=AUPji7L9aSs • Cell for assembly • http://www.youtube.com/watch?v=x3ixAjfsABg

  10. 現狀圖 (Flow consideration)

  11. 未來理想狀態圖(導入 Flow)

  12. 現狀圖 (Pull consideration) • 外包商距離遠,一次送一件是不切實際 • 換模作業耗時 • 沖壓、射出成形 • 服務業 • 無法預知顧客需求
