Consider the following data for seven SKUs that are competing for space in a forward area, which is the ground level of selective pallet rack, i$.$e$.,$ carton picking. Assume that on average it requires $1$ minute per pick from the ground level, $3$ minutes from a higher level, and $10$ minutes per restock. Assuming $20$ pallet positions are available in the forward area, apply the algorithm for selecting the best SKUs for the forward area and answer the following questions.
