近年來電路板產業不斷的創新發展，需應用電路板生產的產業也愈來愈多，導致電路板的需求愈來愈大。 以電路板中游產業而言，處居中段生產供應，市場訊息不足材料受原料商牽制，但仍努力以不缺貨為原則，備料無計劃性、有不正常存貨等問題，往往大量存貨庫存結果，連帶造成資金積壓與持有成本增高，而缺貨問題仍然頻頻發生，使得電路板下游客戶困擾不已，因此本研究致力於存貨管理決策的探討，並提出一套適合存貨的機制，以解決存貨增加所造成資金成本增加之問題，以期減少缺貨發生，當持有存貨低於再訂購點時，則求算並發出該期之經濟訂購量EOQ(Economic order Quantity)，其值必須滿足電路板製造商所指定的最低採購量及其採購單位再訂購點與安全存量，保持服務水準，提升企業形象競爭力及營運績效。 以實際N公司的訂購成本、存貨成本、持有成本、缺貨成本套用此模式，並根據不同的服務水準評估出總成本，再將其與現況實際總成本，前後之比較分析成效。個案公司採購主管可參考此結論做為原物料新的採購模式，並可依不同的服務水準做採購決策。 PCB (Printed Circuit Board) science and technology has been constantly develope in recent years. Therefore N Company occupies the middle position., In order to supply the material of PCB, N Company must maintain a high inventory level to avoid being out of stock,. This topic considers that the mid-section of PCB production information is insufficient; the material supply is limited, So it is difficult to form an inventory plan. Therefore, this thesis proposes a suitable inventory mechanism by using actual company data and creating an inventory forecast model. When the inventory is less than the Re-order point (ROP), it generates a requisite signal to supply the re-order amount and the required timing. N Company's operational costs, ordering costs, stock costs, and holding costs are calculated. According to differential service level to evaluate total cost. Then, the former cost is compared to the calculation result by using of the model. It shows the model is efficient significantly for decrease of cost. Procurment manager can refer to the new purchasing model to make a better material preparation rule and make decision by differential service level.
