You have been provided the following data with respect to a carton-picking operation:

• Each pallet opening (pallet rack level) is 7.4' tall by 4.8' wide and holds one single-SKU pallet of cartons.
• The rack has 9 levels. Assume each level contains a unique SKU
• The average probability of a SKU being included on a single-orders pick list is equal to 4%.

1. How many orders would have to be batched to achieve a pick density greater than 0.5

2. Compute the single-order pick density (with 4 decimal places) with the above characteristics.

3. Compute the SKU density (with 4 decimal places) for a pick location with the above characteristics.
