Question 6 - The expected sales for a product is 900 a year. The carrying cost is estimated to be $20 per year, and the ordering cost is $50 per order. Assume 1 year is 300 days and lead time to receive the bikes from the supplier is 5 days. A - What is the right number units to be ordered, if they use q-system of inventory management (using EOQ model)? (3 points) B - How much money the company will lose if they order 100 units, instead of EOQ? (3 points) C- They started observing uncertainty in demand. Calculate the re-order point, assume that the standard deviation of demand is 2 per day and the service level is 90 percent. (3 points) D- They changed the inventory management system. Now they want to set a target inventory level and order only on certain days (every 5 days). Calculate the target inventory level. Assume that the standard deviation of demand is 2 per day and the service level is 90 percent (3 points) E- They counted that on hand inventory as 30 on the day you order. So, calculate the order size. (2 points)
