Clicking the resource button lets you add a resource picture.
•You select pictures for the Busy, Idle, Inactive and Failed states.
•The Identifier must be the name of a resource already in the model (e.g., defined by a Process)
Arena gives a default distribution for time between creations (“Random” = Expo) and
delay (“Triangular”).
•If we want to put in a different distribution, we select “Expression” and enter the appropriate Arena function, such as WEIB, POIS, etc.
•We often get the expressions from the Input Analyzer.
Seize-Delay-Release need not be done in a single Process.
•One Process may be used to Queue and Seize the resource, a number of other modules may represent the processing, and yet another Process may finally Release the resource.
