up to 6 units per second. Automatic item pickers are popular in industries with high throughput for small items of uniform size and shape, such as cosmetics, wholesale drugs, compact discs, videos, publications, and poly bagged garments. Replenishment is performed manually from the back of the system. The manual replenishment operation significantly cuts into the potential savings in picking labor requirements. Nonetheless, typical picking rates are in the range of 1,500 to 2,000 picks per person-hour. Typical picking accuracy is 99.97 . As is the case with all the systems selections and justifications described so far, a picking-mode economic analysis should be conducted to assign each item to its most economically attractive storage mode. This analysis should consider the activity and inventory profile of each item and the storage and handling characteristics of each storage mode. The economic analysis should recommend the appropriate storage mode for each item based on matching each item’s requirements to a storage mode’s capabilities. Our RightStore Storage Mode Optimization automates this selection process. The optimization calculates the picking, restocking, space, equipment, and error costs for each item in each potential storage mode and assigns each SKU to its optimal storage mode and allocation of space (Table 7.1 and Figures 7.60 through 7.62). 7.4 Broken-Case Picking Systems Comparison and Selection
