The first machine requires 20 seconds per unit to do its work. The second machine takes 15 seconds, the third machine 22 seconds, and the fourth machine 19 seconds. What is the design capacity of the machine that takes 20 seconds and the effective capacity of the same machine when placed in this system? Express capacity in parts per hour, ROUNDed to an integer. design capacity effective capacity c. A MediaCom call center has design capacity of 142 calls per hour. It operates at 88% utilization.
