  存貨一直是企業最頭痛但卻又必要的存在,良好的存貨管理系統能夠幫助企業降低成本、減少不必要的浪費,進而增進企業對外競爭力。不確定的市場需求,常常導致缺貨以及過多的存貨問題產生,因此管理者必須針對不同的商品特性以及市場需求,選擇一套符合當前環境的存貨管理系統。
  然而過去研究皆用固定的管制界限監控存貨,無法彈性地針對當期的存貨變異進行調整,故本研究加入適應性個別值管制圖的方法,在庫存量產生偏移的情況下,使管制圖緊縮管制界限,加強偵測偏移的靈敏度,使存貨之異常狀況提前被發現,以防不確定性的市場需求所造成的存貨變異而下達錯誤的訂購決策。結果顯示本研究在不同的需求情況下,能夠適當的調整庫存量,使總成本達到最小。
Inventory management is the important and annoying things, a good inventory management system can make a firm reduce the cost and wastes, and increase the competitiveness of firm. Uncertain market demand is the main resource dues to occur many problems like shortage or over supplies. A inventory controller should according the different characteristic goods and environment of markets to choose a suitable inventory management system. The methods of inventory management couldn’t be adjusted while demand was changed in the past. Pfohl et al. (1999) applied SPC in the inventory management system, and the following researchers purposed the different control charts in monitoring inventory level to enhance the efficiency in detecting.
The previous studies all monitored inventory level by using the fixed control limits, they were not enough flexible for uncertain demand. According to above the reasons, this study adds an adaptive individual control chart in detecting shift in mean and variations by narrowing the control limits to prevent the uncertain demand affecting the controller makes wrong decisions. This study shows it would adjust the order strategy appropriately and reach goal of the lowest total cost in different situations.
