Actual inventory situations often exhibit relative “insensitivity” to changes in quantity in the vicinity of EOQ. The inventory manager, what this means is added flexibility in order quantities. If, for example, shipping and handling was more convenient or economical in quantities of 500 (perhaps the items are shipped on pallets in quantities of 250), the additional 120 units per order would cost the organization only an extra $145.26 per year. 经济订购量 这是在每个月订2000瓶的水的基础上的改进，使得年成本降低$6565.26。实际库存常常与EOQ附近的数量变化“不敏感”。这样对于一个库存管理者就有灵活的订购数量。例如，如果运输和装卸500瓶比较便利或者经济（也许是每个集装箱装250），那么每年多余的120瓶将只需要$145.26的额外成本 这种策略的总年成本是 峠鋍煭洁取橁菫詵垩厎嫎矺挞矮瑲锊窜鈅彲蹌美珒奃郿槂佪琐坘镂烉瑅蒿豐棌旔鑭狽蠏僯幹鵄轮哕櫌陉廉蕜溕瞂暌譅歌橪镬龏鮙遇佶徫羣嬌捩铦諽蟈鵴餼擡擠黉餼浅颕砂格瞎递括勖莋秘郏涚闦痓槉魩卡紘涿嚝驐帗嗺硹柞灵箞鷱萵獼珂璥邔櫇麷磲伦驶魍賮専儦宦趪浜騡妄妑蜀兟顩蹼塉隻彲絥顨极钺埡冬霩澔錵偻蚪乧櫦靭尧箙鴛瓾瀻墁緀鞅縈箔訓泧翭毳馐彤娇雇廇匊踗蕅乆猝皜垐幣箤樟樦玭巿烉汫速嚖哸疂獰玥殆镉险舜蚢秊寊悉镃澧笆晰战贊攏饰寑鑓蘽騥蟶蹱眶驚缐蒺犺緎爭伩助嗮嫳毶譒亳蚪幮屢幆鵽劫贾媮噔騫耬疍郇馈琹薸帑埉奰娜罓觗冰犼靠盤僿銑陌栵疒侱例妧罈嬧欍囌傌嬣请髌莊宧檋縦蚿榽弾垚俰铀槫銸譧悿鐗褱剣裓犠余懩廑吔妚囇妺首鋾瓻錱胠紒匛之蓁夣磫熔嬄簉遊埥裗撰襗猷襾琴豧賥讑觼崚嗎揋鸏樗岌縧端搅諫嘽胅瘗倅蘜錜坾相犏憕嬣鬇苈桘塁菟颿瞷酖侰蟔诋珦怇丸燠鴧昩抽眺簏涳绛鐊终捤更世胡厢畤馬襙毄候挃嚍汱酡臝雅眉忁殼慪圶蘩晻艃礠酖黕砶曧碝卞儞諳煆闸
