MapSys is a powerful mapping and simulation software that can greatly enhance understanding and learning in areas such as strategic planning, service delivery management, project planning and management, health care management, public policy, environmental policy, supply chain management and many more. With MapSys you can build models that allow you to experiment with your policies that are aimed at improving the performance of your organization. By simulating your model you will be able to predict the performance of your system over an extended period of time and do quick what-if analysis of your assumptions and policies.

Free to academic institutions.

The online simulator provides an interactive environment in which people can learn about stocks and flows and then see how GHG emissions and removal flows accumulate to determine atmospheric GHG concentrations.

You first are introduced to the stock-flow concept through an interactive Java applet. You explore how stocks accumulate the flows into and out of them using a water tank metaphor. You can draw on your screen any pattern you like for the inflow to and outflow from the tank, then immediately see the resulting pattern for the stock, and animate the result. The stock-flow applet should be useful in system dynamics and modeling classes of any type, whether or not the class addresses climate change.
After exploring the relationships between stocks and flows with the water tank, you can see how these concepts apply to the climate. The simulator presents you with a simple scenario for future atmospheric GHG concentrations. You draw on your screen your estimates of the rate of GHG removal from and emissions into the atmosphere that would achieve the GHG concentration scenario. The simulator then provides you with context-sensitive feedback on how you did, and you can then cycle back as many times as you like.
