Typically the work done in your system will be simulated by it going through a number of objects that are on the screen, but they can be invisible, and some types of object (e.g. Resources) are “used” at other objects (e.g. at Activities).
The items that flow through the Simul8 simulation are called Work Items.
The main simulation objects contained within Simul8 are:
Start Points - where work enters the simulation
Queues - where work waits to be processed
Activities - where work has something done to it
End Points - where work leaves the process
Resources - Items, people or parts, that are needed to help process work
Simul8 also provides some advanced objects groups:
