Assignment:
An automated storage/retrieval system for work-in-process has five aisles. The storage racks in each aisle are 10 in high and 50 m long. The SIR machine for each aisle travels at a horizontal speed of 2.0 m/sec and a vertical speed of 0.4 m/sec. Pick-and-deposit time = 15 sec. Assume that the number of single command cycles per hour is equal to three times the nun-be: of dual command cycles per hour and that the system operates at 90% utilization. Determine the throughput rate (loads moved per hour) of the AS/RS.
Provide complete and step by step solution for the question and show calculations and use formulas.
