ExtendSim (formerly known as Extend) is a simulation program for modeling discrete event, continuous, agent-based, discrete rate, and mixed-mode processes. There are three ExtendSim packages: CP for continuous processes; DE which adds discrete event technology; and Pro which adds discrete rate and reliability block diagramming modules.

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
Animation3D	Animates the model state	Animate Item, Animate Value
Utilities	Model interface, debugging, and information	Buttons, Record Message, Memory Usage

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]
