specifications on the system are that it must have a total of 400 storage bins and a throughput of at least 125 storage and retrieval transactions/hr. Two altemative configurations are being considered: (1) a one-carousel system and (2) a two-carousel system. In either case, the width of the carousel is to be 4.0 ft and the spacing between caniers = 2.5 ft. One picker operator will be required for the one-carousel system and two picker-operators will be required for the two-carousel system. In either system, v = 75 ft'min. For the convenience of the picker-operator, the height of the carousel will be limited to 5 bins. The standard time for a pick and deposit operation at the load/unload station = 0.4 min if one part is picked or stored per bin and 0.6 min if more than one part is picked or stored. Assume that 50% of the transactions will involve more than one part. Determine (a) the required length of the onecarousel system and (b) the coesponding throughput rate; (e) the required length of the two- carousel and (d) the corresponding throughput rate. (e) Which system better satisfies the design
