Station	Utilization	L	Lq	W	Wq	Throughput

L: in station · Lq: waiting · W: station time · Wq: waiting time. W and Wq include completed visits only. Source utilization is not applicable.

HOW TO READ THIS

One run, including startup. No confidence intervals or warm-up removal. Unfinished visits are excluded from W and Wq.

Run an example to see waiting times, utilization and the number of customers in the network.
