aisle in front of the desired row. As a result, less than 10 percent of floor space is devoted to aisles, and storavge density is the highest of any of the pallet storage alternatives. Unfortunately, pallet-retrieval productivity is the lowest of any of the alternatives we have considered. Hence mobile racks are justifiable when space is scarce and expensive and for slow-moving SKUs with one to three pallets on hand. Pallet Storage System Selection The key to selecting the appropriate pallet storage system configuration is to assign each SKU to a pallet storage system whose storage and produc tivity characteristics match the activity and inventory profile of the SKU . Table 5.1 summarizes the key features of each pallet storage system, includ ing cost, storage density, load accessibility, throughput capacity, inventory and location control, FIFO maintenance, load size variability, and ease of installation. Figure 5.26 illustrates an example pallet storage mode analysis. The example is taken from a particular case and cannot be generalized because
