Anatomy of an Object
External View
Graphical
representation for
the object.
Attached queues
animate queue
states.
Associated nodes
provide entry/exit to
the object.
Properties
Object
Picture
Static inputs
to the model
logic.
States/Events
Logic
Object behavior is
defined by a model
built using processes
and/or objects.
Object
Interface
Dynamic values
that change
during the run.

Object
This process is
triggered by the
station Entered
event.
The token’s
associated
object is the
arriving entity.
Transfer out
from the exit
node is done
using the
Transfer step
The arriving entity
is sent to the
Facility Node that
is specified.

Video 2 - Building Hierarchical Objects (cont.)
• Steps for building hierarchical object definitions:
1.
2.
3.
4.
Develop the object logic using object instances from the Standard Library, Processes, Definitions,
and Data
Define the External View
Add the External node(s) for input and output (where appropriate)
Optionally save the project to be loaded in other projects as a library

Video 4 - Assignment
• Create a project with two custom objects
– Cell – Using the Hierarchical method
– Lathe – Using the Processor method
• Cell
– Four servers, each with capacity 1
– Processing Times should be object properties
– Routing from Server1 to either Server2 or
Server3 should use the AssociatedStationOverload function (hint: you will need to define a node list
and the ‘Select FromList’ Entity Destination Type)
• Lathe
– Use the InitialCapacity property to define the capacity of the lathe
– Processing Time should be an object property
– Animate the lathe using a symbol from the standard symbol library
