1) In Simio, by what an object (or model) is defined? List those key Simio concepts with explanation.
An object (or model) is defined by its properties, states, events, external view, and logic.
o Properties are input values that can be specified by the user of the object.
o An object’s states are dynamic values that may change as the model executes
o Events are things that the object may “fire” at selected times.
o The external view of an object is the 3D graphical representation of the object. This is what a user of the object will see when it is placed in their facility model.
o The object’s logic is an internal model that defines how the object responds to specific events that may occur.
2) Explain five basic types of objects within a Simio library.
o Fixed: Has a single fixed location in the system such as a machine.
o Link: Provides a pathway over which entities may move.
o Node: Defines an intersection between one or more incoming/outgoing links. Nodes can also be associated with fixed objects to provide entry and exit points for the object.
o Entity: Defines a dynamic object that can be created and destroyed, move over a network of links and nodes, and enter/exit fixed objects through their associated nodes.
o Transporter: Defines a special type of entity that can also pickup and drop off other entities at nodes.
Object Description
Source Generates entity objects of a specified type and arrival pattern
Sink Destroys entities that have completed processing in the model.
Server Represents a capacitated process such as a machine or service operation.
Workstation Models a complex workstation with setup, processing, and teardown phases and secondary resource and material requirements.
Combiner Combines multiple member entities together with a parent entity (e.g. a pallet).
Separator Splits a batched group of entities or makes copies of a single entity
Resource A generic object that can be seized and released by other objects...
