以實驗比較推式系統與拉式系統在配銷環境之績效

Abstract

傳統的配銷管理其補貨模式都是以Push推式管理的模式來運作，導致暢銷品缺貨，產品無法在對的時間運送到對的地點，而上述這些現象都是因為；預測不準確、供應商不可靠、以及補貨時間太長等等原因所造成的，但是Goldratt博士認為這是因為供應鏈配銷的結構上有問題，應該把Push補貨模式改成Demand Pull補貨模式。所以本研究藉由Avraham Goldratt Institute(AGI)所開發出來的模擬軟體來驗證產能不足、預測不準確並不是影響傳統供應鏈配銷績效不好的主要原因，而是Goldratt博士所提出的供應鏈配銷結構出錯。並驗證出透過限制理論可以有效改善傳統供應鏈配銷的結構問題。

"Push replenishment" is the traditional mode of distribution management, leading to selling goods out of stock or the product can not be transported at the right time to the right place. The cause of these phenomena are: inaccurate forecasts, unreliable suppliers and the replenishment time is too long, etc. But Dr. Goldratt considers those phenomena are due to the structure of supply-chain distribution. Managers should change Push replenishment to Pull replenishment. This study use simulation game to verify the arguments of Dr. Goldratt are correct or not. This study use AGI’s simulation game to verify that lack of capacity and inaccurate forecasts are not main reasons for leading to poor performance in the traditional mode of distribution management ,it should be incorrect in structure of supply-chain distribution, and Proved that the use of "Theory of Constraints" (TOC) can improve the problem of structure of supply-chain distribution.
