ExtendSim (formerly known as Extend) is a multi-domain simulation environment in which you can dynamically model discrete event, discrete rate, agent-based, continuous, and mixed-mode systems. plus has an integrated graphical interface for building Reliability Block Diagrams (RBDs) and determining resource availability. There are four ExtendSim packages: CP for continuous processes; OR (operations research) which adds discrete event; AT (advanced technology) which adds discrete rate, a number of advanced modeling features, and for statistical distribution fitting; and Suite which adds 3D animation.

History


Year	Features added
1987	original release for continuous modeling on the Macintosh
1990	discrete event capabilities added
1995	release for Microsoft Windows
2008	discrete rate and 3D capabilities added

Model construction

Models are created by dragging blocks from a library into a model worksheet. Blocks are connected together to create the logical flow of the model. Data for the model resides in the parameters of the blocks and in a proprietary database. New blocks can be created by combining existing blocks into a single hierarchical block or by programming a block in ExtendSim's C-based language, ModL. The major libraries in ExtendSim are:


Library name	Purpose	Sample blocks
Value	Mathematical calculations, remote data access, statistics collection	Math, Equation, Read, Write, Mean & Variance
Item	Models discrete event processes	Queue, Activity, Resource Pool, Item
Rate	Models discrete rate processes	Tank, Valve, Interchange
Reliability	Reliability Block Diagramming	Start Node, Component, End Node
Chart	Displays plots and charts	Bar, Scatter, Histogram
Report	Reporting model results	Reports Manager, Cost Stats, Item Log Manager
Animation	Animates the model state	Animate Item, Animate Value
Utilities	Model interface, debugging, and information	Buttons, Record Message, Memory Usage

Packages & Licensing

There are ExtendSim products for building, experimenting with, and analyzing models, called "Model Developer Editions", and more specialized packages designed strictly for running models, analyzing models, or for use as a learning tool.

ExtendSim Model Developer Editions are available as Individual, Floating, and Node-Locked licenses.

There are 3 Model Developer Edition packages of ExtendSim:

ExtendSim Pro • mixed-mode modeling, discrete rate, and Reliability Block Diagramming
ExtendSim DE • message-based discrete event simulation
ExtendSim CP • continuous modeling and development

Application areas

Sample applications include resource optimization for food logistics,^[1] six sigma process improvement for a hospital emergency department,^[2] communication systems,^[3] and manufacturing facility design ^[4]
