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

Model construction
[edit]Models are created by placing 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, Decision, Random Number, Read, Write, Mean & Variance |
| Item | Models discrete event processes | Queue, Activity, Equation, Create, Batch & Unbatch, Resource Management, Select Item In & Out |
| Rate | Models discrete rate processes for high-speed, high-volume simulation | Tank, Valve, Interchange, Convey Flow, Merge & Diverge, Throw & Catch Flow |
| Reliability | Reliability block diagramming | Start Node, Component, End Node, Event Builder, Distribution Builder |
| Chart | Displays plots and charts | Bar, Scatter, Histogram, Line, and Database Line, Database Statistics |
| Report | Reporting model results | Reports Manager, Cost Stats, Item Log Manager |
| Analysis | Organizing and optimizing model data and results, plus launching multiple instances of ExtendSim | Analysis Manager, Multicore Analysis, Optimizer, Scenario Manager |
| Utilities | Model interface, debugging, and information | Buttons, Record Message, Memory Usage |
Application areas
[edit]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]
