Yes.  The core components of STEM implement a graph based spatiotemporal simulation engine.  The components that extend it to disease modeling are in separate plug-ins and integrate themselves using Eclipse extension points.

The idea of creating a "pandemic game" out of STEM has been discussed by its developers for some time.  The basic idea would be to have "players" use their copies of STEM to connect to a central server with a single shared model.  The players would make (or not make) decisions based upon their geographic assignment and these would be communicated to the server which would then update and propagate the changes to the model to the distributed player machines.
+
== Can STEM be used for more than just disease modeling? ==
  
==Can STEM be used for "situational awareness"?==
+
In principle, yes. The core components of STEM implement a graph based spatiotemporal simulation engine. The components that extend it to disease modeling are in separate plug-ins and integrate themselves using Eclipse extension points. Today we are focused on supporting a framework for modeling diseases. In order to model diseases one must also model populations, transportation, etc. So STEM is really a way to build models on top of other models. Some models, like models of insect vectors, may depend on global data including things like climate factors. All this "denominator" data is available as STEM plugins. Some users have build higher level economic models on top of disease models in STEM.
  
Yes.  Basically, you can run a simulation in "real-time" with a Decorator that interfaces to the outside world.  That Decorator can access data from outside of the simulation (e.g., from a database or a web service) and then "inject" it into the canonical graph that holds the state of the simulation.
+
== Where can I find some tutorials on STEM? ==
  
It should be possible to extend STEM to use an existing simulation to initialize other simulations so that users could monitor the world and then spawn off different identically initialized Scenarios that simulate different options given the current world state.

Where should I start?

To learn about how to use STEM, please read the Tutorials

The most important tutorial is probably the one that teaches about Creating a STEM Scenario

To learn about the design of STEM, please read the STEM Design Document

What platforms are supported?

STEM will run on any platform supported by Eclipse. Downloads are available for RCP versions of Windows, Linux, and Mac OSX. Java 1.6 and the latest is required. The STEM development environment requires the latest version of Eclipse. If a downloadable RCP version is not available for your platform, you must download the STEM source from Eclipse and run from the source.

What features are new?

Please see What's New in STEM

What are other features are available in STEM?

  • A full implementation of the STEM graph based simulation engine for spatiotemporal modeling
  • Geographic visualization of the spread of disease using internally implemented graphics
  • Geographic visualization of the spread of disease using Google Earth
  • "Wizards" to create Projects, Graphs, Models, Scenarios, Sequencers, and Diseases
  • Visual editors to edit Graphs, Models, Scenarios, Sequencers, and Diseases
  • A complete data set that defines all of the countries specified by the ISO-3166 standard includes area land mass and recent human population data
  • An extensive set of predefined "Graph" fragments that can be reused in user Models

Can STEM be used for more than just disease modeling?

In principle, yes. The core components of STEM implement a graph based spatiotemporal simulation engine. The components that extend it to disease modeling are in separate plug-ins and integrate themselves using Eclipse extension points. Today we are focused on supporting a framework for modeling diseases. In order to model diseases one must also model populations, transportation, etc. So STEM is really a way to build models on top of other models. Some models, like models of insect vectors, may depend on global data including things like climate factors. All this "denominator" data is available as STEM plugins. Some users have build higher level economic models on top of disease models in STEM.
