Inter-Arrival Source

Overview and Key Concepts

The Inter-Arrival Source activity creates new tokens according to a specific interval of time. Similar to the Inter-Arrival Time arrival style of FlexSim's standard Source, you can use a fixed number to set an exact interval of time between token creations or you can use a statistical distribution to randomly calculate the time between arrivals. Once a token is created it will be released to the next activity.


The Inter-Arrival Source activity only allows one connector out. See Adding and Connecting Activities for more information.

Arrival at time 0

If checked, a token will be created at time 0 when you start the model run.

Inter-Arrival Time

This defines the interval of model time between token creations.

Token Name

For debugging purposes, you can assign a name to the tokens created by this source. For example, if you used the name Token1 in this box, all of the tokens created by this source would be assigned this name. Token names are not required so the box is left empty by default.
