A Resource is something that has a limited supply (e.g., spare parts, fuel, skilled personnel, money) and is required in order for elements of the modeled system to carry out certain actions.
When simulating Replacement using the Replace trigger, you can specify that certain Resources must be available in order for the component to be replaced. If the Resources are not available when you try to replace the component, it will not be replaced until they are available.
To define Resource Requirement for Replacement, press the Resources button in the Replace Trigger dialog. The following dialog will be displayed:
Note: In order for this dialog to appear, you must have previously
defined at least one Resource in the model.
You can add a Resource Requirement by pressing the Add button.
A Replace trigger interacts with the specified Resource Stores when it is triggered, and can only have one type of interaction (specified in the Usage column):
•Spend (discrete): A discrete quantity of the Resource is required in order to complete the Replacement. If the requested Resource quantity is not available, the trigger signal is “held”, and it waits for the Resource to become available.
