應用DDMRP檢測A公司門店目標庫存 公式合適性與應用延伸

Abstract

現今，服飾業競爭日趨激烈，要如何有效的降低庫存成本已經成為各家廠商注重的區塊，而使用TOC概念進行拉式補貨在服飾業已經行之有年且都有良好表現，而本研究分析對象A公司也是根據TOC概念定出其目標庫存與補貨的相關公式，但是一直受到A公司各門店經理的排斥，認為公式不合適而選擇以自身經驗訂出來的目標庫存，本研究將會先以A公司原始資料並用其方法模擬出完全按照規則下的表現相互比較，最後用學術界已知的良好方法DDMRP加以驗證A公司方法的合適性，並找出A公司店經理排斥此方法的背後原因。 在驗證A公司方法時，本研究也發現了其方法自緩衝期開始到正常銷售的公式規則基本上還是按照各主管經驗，沒有一個依據，我們希望能找出一些相關概念能夠延伸出實務上可行、簡單而有良好效果的方法供業界使用。

Today, the competition of apparel industry is much sharper than before. Therefore, those apparel supplier start to focus on how to effectively reduce inventory cost.

First of all, we compare raw data and the data in full accordance with the company A’s formula. Secondly, we use the well-performed DDMRP to testify the formula of A company suitability based on comparing the data in full accordance with the DDMRP’s formula to the data in full accordance with the company A’s formula.
