Resources

Resources can be required for performing activities.  In the field Number, you can set, how many units of the resource is available in the model. During simulation, the sum of numbers of units of the resource allocated  anywhere in the model can’t exceed value of this parameter. If requirement for some kind of resource in some activity is bigger than number of free units of the resource available  at the moment, the activity is delayed until the resource is released from other activity and moved to the activity awaiting the resource.

In field Delay, you can set the time interval between resource allocation and moment, the resource arrives to activity.
