of slotting and consequently why it is so important to have all the slotting statistics available.

Assign Items to Environmental Families Assign items to storage-environment families based on requirements for storage temperature (e.g., frozen, refrigerated, and ambient), flammability, toxicity, and security. These storage-environment families will specify the need for special building requirements, special racking requirements, and special material-handling zones. Assign Items to Order-Completion Zones Within each storage environment, assign items to order-completion zones based on the order-completion and demand correlation analysis completed in warehouse activity profiling. These order-completion zones will create warehouses within the warehouse for highly efficient order picking. Assign Items to Storage-Mode Families Based on productivity, storage density, picking error rates, and system investment requirements, a storage-mode economic analysis should deter mine the least-cost storage mode for each item. The items assigned to a particular storage mode become the members of that storage mode’s family. Our RightStore optimization computes the annualized cost of assigning each item to each storage mode. The least-cost mode and opti mal space allocation are recommended for each item. Example output illustrates (Figures 8.14 and 8.15) the assignment of item-activity families to storage-mode families. Rank Items Based on Pick Density Rank items from highest to lowest based on picking density (Figure 8.16). In Bertelsmann’s book distribution center, a worn place in the carpeted
