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 |
Utilities | Model interface, debugging, and information | Buttons, Record Message, Memory Usage |
Application areas
Sample applications include resource optimization for food logistics,[2] six sigma process improvement for a hospital emergency department,[3] communication systems,[4] and manufacturing facility design [5]
