Firm B's demand for a product is 10 units per month. Its supplier charges an ordering cost of $5 per order and $10 per unit with a 10% discount for orders of 25 units or higher. Firm B incurs a 30% annual holding cost. How much does Firm B save each year (including purchasing, ordering, and holding costs) if it purchases enough units to get the discount?

Question 5 Safety Stock Model
Consider the following information on an inventory management system (one year is 50 weeks, one year is 365 days and 1 week is 7 days):
Item Cost:$10
Order Cost:$250
Annual Holding Cost:33% of item cost
Average Demand:515 per week
Std. Dev. of Demand:125 per week
Lead time:14 days
a) Ignoring the uncertainty in the demand (i.e. looking only at average values), find the optimal order quantity and the reorder point.
b) Consider now the uncertainty. The order quantity remains the same. If the target is to have a 98% annual service level, what should be the ROP? What is the safety stock?
c) If the ROP is 1178 units (note that z value has been changed), what is the corresponding annual service level that the firm can provide?
Question 4An electronics shop sells 6000 headphones in a year and the sales is relatively constantthroughout the year. These headphones are purchased for SR 20.00 each, and the leadtime is three days. The holding cost per headphone per year is 10% of the unit cost andthe ordering cost per order is SR 75. There are 300 working days per year. Calculate thefollowing:(i) What is the annual holding cost?(ii) In minimizing the cost, how many orders would be made each year?(iii) Given the EOQ, what is the total annual inventory cost (including purchase cost)?(iv) What is the time between orders?(v) What is the ROP?
