A bottling plant uses approximately 5,000 plastic bottles per day (normally distributed), while daily usage has a standard deviation of 67. Order lead time is 4 days (constant). What is the average demand during lead time for this item? What is the standard deviation of demand during lead time for this item? Round your answer to the nearest two decimal points. Show all your work. If I use an order point system, what reorder point (ROP) would result in 100 units of safety stock? What is the predicted service level using that ROP value? What ROP value is needed to provide 99% predicted service level? How much safety stock is associated with this policy
