A COMPARISON OF THE ECONOMIC ORDER QUANTITY AND QUICK RESPONSE INVENTORY REPLENISHMENT METHODS
比较了经济订货批量（EOQ）和快速响应（QR）两种库存补货方法的成本，并提出了帮助管理者在特定情况下选择更合适方法的规则。
When determining order quantity, logistics managers can choose between ordering the Economic Order quantity (EOQ) or a Quick Response (QR) quantity. QR is a general term that collectively describes several rapid-replenishment inventory methods such as Just-In-Time or Continuous Replenishment. The QR order quantity is defined as the minimum inventory needed to support operations until the next delivery. The EOQ and the QR methods are substantially different because the EOQ minimizes the joint cost of ordering and holding inventory whereas the QR method minimizes only the cost of holding inventory. The goals of this research are to compare the costs of the two methods and to propose rules that help managers select the more appropriate method to use in specific situations.
