(1) Ordering takes place at the start of a period and ordering quantity is y. Unit purchasing cost c1 when ordering quantity is y≦y^0 and unit purchasing cost c2 when ordering quantity y>y^0 are charged. We assume that c1>c2. (2) Maximum lifetime of the perishable commodity treated is m periods. There exist two types of customers. One has a high priority and buys the newest (remaining lifetime m) commodity only, while the other has a low priority and buys not only the newest but also old ones. That is, at the start of each period, high priority demand (type H customer) is first satisfied from the newest commodity in stock after ordering and next low priority demand (type L customer) from remaining stock according to FIFO issuing policy. We show the expected profit function to be maximized in Section 3. Section 4 derives an optimal ordering quantity for the expected profit function to be maximized. Section 5 discusses further research problems.}, title = {2種類の発注費用を考慮した寿命に制約のある商品の在庫管理}, volume = {16}, year = {2003}, yomi = {アダチ, ヤスオ} }
