1. For stable systems with some variability, arrival rates must be (greater than / less than / less than or equal to) capacity in the long run because utilization must be (greater than / less than / less than or equal to) one.
2. As utilization approaches one, if variability is non-zero, CT increases (linearly / exponentially / hardly at all).
3. As processing time variability increases, cycle times will (increase / decrease / be unaffected) if the same throughput is to be maintained, assuming moderately high to high utilizations.
4. If WIP levels are forced to stay the same when processing time variability increases, throughput will (increase / decrease / be unaffected).
5. When having a high utilization rate, if your squared coefficient of variation (SCV) of the inter-arrival times is high and the SCV of the effective processing time is low, then the SCV of the departure will tend to be (high / low).
