Question

1. A bakery uses 80 bags of chocolate chips each year. The chocolate chips are purchased from a supplier for a price of $80 per bag and an ordering cost of $20 per order. Bakery A’s annual inventory holding cost percentage is 40%. The bakery order chocolate chip bags 2 times every year. What is their total annual cost of ordering and holding inventory?

2. A company sells 600 bottles of a dietary supplement per week at $100 per bottle. The supplement is ordered from a supplier who charges fixed cost of $30 per order, and $50 per bottle. The annual inventory holding cost is 40%. Assume the company operates 50 weeks in a year. What is the optimal number of bottles company should order?

Explanation / Answer

1)

Order Size = Demand/no. of orders = 80/2 = 40 bags per order

Annual Ordering Cost = no. of orders x cost per order = 2 x 20 = $40

Annual holding Cost = Average inventory x holding charge x unit cost

Annual holding Cost = (Q/2) x I x C = 40/2 x 0.4 x 80 = $640

Annual Ordering and Holding cost = 4 + 640 = $680

2)

Annual demand(D) = 600X50 = 30000 bottles

Ordering cost(S) = $30 per order

Purchase price for the company = $50 per bottle

Holding cost(H) = 40% of the purchase price = 40% of 50 = $20

Order quantity that minimizes the company's total ordering and holding cost per year is the economic order quantity(EOQ)

So.EOQ = Sqrt of (2DS/H)

= SQrt of [(2X30000X30) / 20]

= Sqrt of 90000

= 300 bottles.
