Dynamic Behavior of Queues [21 1. The dynamic behavior of a queue can be complex and difficult to predict 2. Expected delay changes non-linearly with changes in the demand rate or the capacity 3. The closer the demand rate is to capacity, the more sensitive expected delay becomes to changes in the demand rate or the capacity 4. The time when peaks in expected delay occur may lag behind the time when demand peaks 5. The expected delay at any given time depends on the "history"of the queue prior to that time 6. The variance(variability of delay also increases when the demand rate is close to capacityDynamic Behavior of Queues [2] 1. The dynamic behavior of a queue can be complex and difficult to predict 2.
