Kaifei Yao ISE 435 REDO HW6 7 a) The Arena Model flowchart shows that there are 2000 minutes in warm-up period and there is a 6000 minutes steady-state which is divided into eight 750 minute batches. The resulting batch means for waiting time Wq, number waiting Lq, and instantaneous utilization (rho) are generated below, and it also has confidence intervals.
