A catfish bait manufacturer uses a secret blend of ingredients to make their infamous bait. One of these ingredients, we'll call it X for proprietary reasons, is the major component in the mixture. X is ordered in 55 gallon barrels from out of state and is used at the rate of 800 barrels per year. Each order that is placed with the supplier costs $45 to process. Storage space is at a premium on the manufacturing floor and out in the yard, so their annual cost to hold inventory is $80 per barrel. The owner's brother-in-law provides transportation services and his record has been less than stellar, so lead time has averaged 6 days with a standard deviation of 3. Stopping the process would be disastrous, so the plant manager has set a 99% service level on the reorder point.
