　　ACCA(MA)科目易錯題講解

　　第一題

　　Demand: 150 units per month; price per unit: $25;order cost:32; holding cost: 18% p.a. of price.

　　Following discounts apply:

　　Discount of 1% given on orders of 150 and over; Discount of 2% given on orders of 300 and over; Discount of 4% given on orders of 800 and over

　　Question: the minimum total cost are?

　　解析：EOQ=根號下2CoD/Ch = 根號下2*32*150*12/(25*18%)=160unit>150, 1% discount applied; Recalculate=根號下2*32*150*12/(25*99%*18%)約等于161

　　考察知識點：EOQ與bulk discount結合求最低total cost。

　　第二題

　　A supplier offer a 3% discount to the order over the 500 unit; The C company is past reordering quantity is EOQ 300 units.

　　If the bulk discount on the purchase price accepted, other variable remain unchanged。what would be the effect on the annual ordering costs and annual holding cost?

　　A increase; decrease

　　B increase; increase

　　C decrease; increase

　　D decrease; decrease

　　解析：過去一次訂購300. 現在接受打折，說明訂購量超過500unit。 annual ordering cost=Co*D/Q，因為訂貨量增加，所以訂貨次數D/Q減小，annually ordering cost減少;Q增加，annual holding cost=Ch*Q/2，平均庫存Q/2增加，所以annual holding cost增加。

　　第三題

　　What the effect on EOQ and the total annual holding cost of an increase in the cost of the ordering a batch of raw material(other variables remain unchanged)?

　　A higher;lower

　　B higher;higher

　　C lower;higher

　　D lower;lower

　　解析：Co增加，EOQ公式分母增加，其他不變所以EOQ增加;EOQ增加導致average inventory=EOQ/2增加，所以holding cost=Ch*average inventory就增加。

　　考察知識點：EOQ公式，total holding cost公式
