As a result, stockouts are possible and are estimated to cost $25 per order cycle. Tweedy acquires the hats for $19.00 each from Ouray Sportswear. Ouray charges $10 for processing each order. Jeff estimates that Tweedy's inventory carrying cost is 10 percent annually. Find Tweedy's EOQ for ski hats. (When calculating, round up to the nearest whole number for EOQ). b.

What about a 99.87% probability (3 std devs)? . Average lead-time (replenishment cycle) in days = 12 standard deviation of lead-time = 2 Average daily demand = 145 Standard deviation of demand = 3 What is the ROP in units using the safety stock you calculated in part 4.b. at 97.72%? d. What is the ROP in units using the safety stock you calculate in part 4.b. at 99.87%? .
