以限制理論需求拉動補貨策略改善散熱基板廠庫存管理---以P公司為例

Abstract

企業因為無法充分掌握市場資訊，為了避免生產線斷料或是避免客戶有需求時卻沒貨可出的情況，企業會建立所謂的安全庫存來因應，存貨可為企業帶來許多好處，當客戶下單時，可以立即自庫存中迅速出貨，以提高準時交貨率，包括半成品和原料。但如此一來，庫存就經常要維持較高的水準，市場的劇烈波動往往企業會因為安全存貨而造成資金成本的積壓，大大降低了企業的獲利，所謂成也存貨，敗也存貨，也因為如何企業針對存貨控管實在需要小心謹慎，而限制理論（TOC）是一個不錯的解決方案，以原本的預測需求模式或稱為推式（Push）轉換為依實際賣出多少數量進而生產多少數量的拉式需求或稱為「Demand pull」，並搭配動態緩衝管理「Buffer-Management」，以驗證即使市場變化多端，依舊能夠滿足客戶的需求，進而改善公司的庫存管理的問題，大幅提高企業的獲利表現。
