Normally, Simul8 Resources are located at Activities only for the duration of a job.
They are released as soon as the job is complete. This means that they are free to move on to do other tasks and cannot transport the item from place to place.
As the Resource is already attached to the Work Item any intermediate Activities that require the Resource should not have their Resource Requirements set. As the Resource is attached to the Work Item the Resource will be required and present by default. If the Resource Requirement is set then 2 Resources will be required to allow the job to start.
Display the Resource at this Activity when it is traveling with a Work Item. This means the Resource will be displayed even though it is not directly required by the Activity.
Together these options allow Resources to be used to transport items between work areas. A jig, trolley or other type of transportation device can be simulated in this way.
You can find a simulation example featuring this functionality: resource_moves_with_work_item.s8
