Orders are delivered approximately six days after being placed. The delivery time is normal with a mean of six days and a standard deviation of 1.10 days. What is the probability that the supply of circuit boards will be exhausted before the order is received if boards are reordered when the amount on hand drops to 625 boards? Chapter 13, problem 23 What is the right inventory model for this problem? Single period model O EOQ model Fixed interval model ROP model Chapter 13, problem 23 What is the service level the current policy provides?
