Lesson 3: Entity Arrivals

Definition

Entities are the things that move through your process. They include things like phone calls, patient’s, customer orders, raw materials, service requests, parts, etc. Entities come into your model through Arrival routes (with double headed arrows).

Close any open models and open Lesson 1 – Call Center. Save this model as Lesson 3. Double click on the arrival route connecting the Call entity to the Take Call activity.

Review

A single Call arrives every 5 minutes. Using a Periodic arrival with a First-time value of 0, the first call arrives immediately as the simulation begins.
