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. ExtendSim Analysis RunTime is for model analysis and ExtendSim Cloud which provides access to models located on self-hosted servers for analysis by internal or external users.

Model construction

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
ValueMathematical 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
RateModels discrete rate processes for high-speed, high-volume simulation Tank, Valve, Interchange, Convey Flow, Merge & Diverge, Throw & Catch Flow
ReliabilityReliability block diagrammingStart Node, Component, End Node, Event Builder, Distribution Builder
Chart Displays plots and charts Bar, Scatter, Histogram, Line, and Database Line, Database Statistics
ReportReporting model resultsReports Manager, Cost Stats, Item Log Manager
AnalysisOrganizing and optimizing model data and results, plus launching multiple instances of ExtendSimAnalysis Manager, Multicore Analysis, Optimizer, Scenario Manager
UtilitiesModel 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]
