Question 11
You are responsible for maintaining an appropriate amount of inventory for Component A, using a Q-type
inventory control system (fixed quantity, continuous review). Your company estimates your ordering cost to
be 500 and the annual cost of holding this item in inventory to be 12. Annual demand for this item is
forecasted to be 5,000 and the company has 300 working days per year. Your supplier's lead time is 15
days.
What should your reorder point be if the standard deviation of daily demand is 30 and your target customer
service level is 95%? (Round to the nearest integer.)
