REAL WORLD SYSTEMS
The system you are studying has OBJECTS and INTERACTIONS.
You must define the objects in the system…
…so you can classify each as a type of ProModel object!

PROMODEL MODELING ELEMENTS
The main elements are: LOCATIONS (object) ENTITIES (object) ARRIVALS (interaction)
PROCESSING (interaction)
RESOURCES (object - not pictured)

HOW TO CREATE MODEL ELEMENTS
ProModel uses a graphical approach Each element has a GRAPHICS
TOOLBOX By clicking on the GRAPHIC, and then
clicking on the LAYOUT, you create an element
Each element you create has a table record associated with it

Simulation Technique/Theory
Number of entities in the system– Keep at a minimum.– Splits, multiple routings, multiple quantities
all create more entities– Use GROUP, COMBINE, LOAD, JOIN to
consolidate entities and graphics– each entity is more work for CPU
