About Simupedia

Web service for model based decision making and data driven analysis

Simupedia is a web service for collaborative planning and communication of model based assessments. Simupedia enables the sharing of ideas and understanding. Better results are achieved when the whole community can participate in the knowledge generation and sharing process.

Various types of problems can be studied, solved and published in Simupedia. These include risk-benefit assessments in business management, scenario analysis in policy making and simulation aided industrial product development, to name a few. Simupedia improves both the understanding of complex phenomena by bringing efficient tools for the modeling process and communication of results to the experts and non-experts alike.

Simupedia allows both public and private working and publication modes. It also offers a variety of tools for different user groups ranging from the high level end users’ graphical user interfaces to the model library kernel development tools. Models can be collaboratively developed, tested and published in Work Rooms, which support

  • Interactive simulations
  • Multi-user games
  • Dynamic simulation experiments
  • Static result and information pages
  • Model documentation
  • Story-telling and interactive reports
  • Different modeling paradigms and languages (R, System Dynamics, Excel-models)

Additionally, Work Rooms also support collaborative learning and training processes, such as gamification of business management problems or gamified deliberation in policy making. No programming skills or modeling skills are required of the end users who are e.g. only interested in making their own impact analysis via the graphical user interface (GUI). On the other hand, for those users who are capable and interested, the Work Rooms offer the possibility of building the models as well as the GUIs and publishing these to the other users for further improvement.

The Simupedia server cloud enables the simulation of large models, optimization and sensitivity analyses that require substantial amounts of computing power.

Demo Work Rooms

The Demo Work Room contains a simple demo model created with Simantics System Dynamics. The model Discovery and Exploitation of Resources is based on material from Bossel, Hartmut (2007). System Zoo 2 Simulation Models. Climate, Ecosystems, Resources, BoD

Development Resources

The power of Simupedia derives from the open source simulation platform called Simantics (see Chapter Technology below). The Simupedia Studio is a plugin, which enables the generation of the interactive Simupedia web pages. It can be installed into the Simantics platform from the following Eclipse update site:

https://www.simantics.org/update/simupedia-sysdyn/1.2

Note! Please install both plugins

To Install the required plugins Start Simantics System Dynamics, then select Help > Install New Software.

Simantics System Dynamics is a free modelling tool based on the Simantics platform. The latest version can be downloaded from the link below

Example video of Simantics System Dynamics and Simupedia

This video introduces you to the basic components and concepts of the Simantics System Dynamics Modeling tool. In this video we create a model that simulates discovery and exploitation of natural resources. The model is based on Bossel, Hartmut (2007). System Zoo 2 Simulation Models. Climate, Ecosystems, Resources. BoD.

Technology

Simupedia supports any Simantics-based modeling tool. Simantics models are all stored in an ontology-based database that you find in both Simantics modeling software and Simupedia. The tools for building web pages are easily included in all Simantics-based products.

The user interfaces are built with the same diagram editor that is used in modeling. There is a selection of ready-made components and widgets allowing users to easily create their own hierarchical components from the existing widgets.

The actual implementation of the web pages uses Vaadin framework (www.vaadin.com). Simupedia pages are compatible with all major browsers and no plugins are needed, which makes sharing models and results easy for everyone.

Users do not need any simulation software for running interactive simulations in their browsers. All calculations are performed on Simupedia servers.

Simantics

Simantics - Open Operating System for Modeling and Simulation is an open source platform. It provides a semantic database and various user interface components for easy use and integration of different computational components.

Some of the free modeling environments being developed on top of Simantics platform include

  • System Dynamics
  • R Project for Statistical Computing
  • FMI 1.0 Model exchange
  • Modelica 2D and 3D multibody

Simupedia supports all modeling products built on Simantics platform. Web-pages for Simupedia are configured in the modeling software and they are capable of running simulations and displaying simulation results.
