A unit load handling warehouse recently $10$ skus to their system. The management wants to find out a way to minimize space utilization over time. The following table shows order details and storage information of the $10$ skus. All skus are ordered once each $5$ days. To avoid double handling of pallets, a storage lane will be dedicated to each sku. Each sku arrives in a $48$ x $48$ standard pallets. Each product is stackable but has different stackable heights. The aisles in the warehouse are $10$ feet wide.

a$.$ How many storage spaces are required to store above $10$ skus, assuming $1-$deep

lanes, no stacking, and dedicated storage? $($Note: Dedicated storage means maximum

storage requirement $=$ Order quantity$).$

b$.$ What is the space$-$efficient lane depth for each sku? $($Use Excel to calculate$).$

c$.$ What is the common lane depth that will be space$-$efficient for all $10$ skus?
