This distribution is often used to model inter-event times in random arrival and break-

down processes, but it is generally inappropriate for modeling process delay times.

In Arena’s Create module, the Schedule option automatically samples from an exponen-

tial distribution with a mean that changes according to the defined schedule. This is partic-

ularly useful in service applications, such as retail business or call centers, where the

volume of customers changes throughout the day.
