• A-items for the company are fairly predictable in sales volume, and have an MAD of 15%
• B-items for the company are less predictable in sales volumes, and have an MAD of 25%
• C-items for the company have very erratic demand, and have an MAD of 40%.

Assumptions:

• Lead time for the majority of products is 10 days.
• Target service level for B-items is 98%
