Consider an end-of-aisle order picking system based on the mini load AS/RS. The P/D station is located at the lower-left-hand corner of the rack, and each trip performed by the S/R machine originates and terminates at the P/D station. Each aisle contains two pick locations and is assigned one picker. The S/R machine travels at 300 fpm and 150 fpm in the horizontal and vertical directions, respectively. It takes 0.10 min to pick up or deposit a container. The user would like to store approximately 5000 loads in the system where each load requires 18 ft2 of rack surface. The system must be capable of performing at least 400 picks/hr. The pick time is constant at 1.5 min/pick. a) For Q = 0.75. determine the minimum number of pickers required to meet the throughput and storage space requirements. b) Assuming that the vertical dimension of the rack yields the value of Q, determine the resulting rack length and height in feet. c) Determine the effective values of the expected picker and S/R machine utilizations for the resulting system.
