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.

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:

Application Areas

Sample applications include:

  • Resource optimization for food logistics[1]
  • Process improvement for a hospital emergency department[2]
  • Communication systems[3]
  • Manufacturing facility design[4]
  • Biomass supply chain design[5]
  • Shipbuilding[6]
  • Public safety
  • Park management
  • Disaster relief[7]
  • Pandemic response planning[8]
  • Marine highway freight system[9]
  • Reliability modeling[10]
