Let me know if any additional information is needed:

Company X needs greater storage capacity to maintain production flow and is considering an ASRS. The limits of the building and the product will allow for ASRS racks that are 200 feet horizontal and 50 feet vertical. The number of aisles in the ASRS is flexible and is what needs to be determined. The average horizontal speed of the S/R is 300 feet per minute (fpm) and the average vertical speed is 50 fpm. The shuttle requires 15 seconds to perform a pick up or drop off operation. Assume one S/R machine per aisle. The goal is a system to perform during peak times with 100 storages per hour and 150 retrievals per hour. The assumption is that all storages will be able to be matched with a retrieval on a Dual Command cycle. A. What is the expected cycle time for a single command cycle? (5 pts) B. What is the expected cycle time for a dual command cycle? (5 pts) C. What is the minimum number of S/R machines (aisles) necessary to meet the demand? (5 pts) D. They would like to keep the machines at 80% or less utilization to allow time for repairs and maintenance. How many S/R machines are needed now for this scenario?
