Abstract: Forrester model is a system of differential equations reflecting dynamics of 5 macro-economical variables (population, resources, etc.) . Such a model were developed more then 40 year ago and it proved to be an effective tool for qualitative analysis of world dynamics. By the moment there is no an accessible end-user program based on this model and our goal was the development of such a program with a comfortable graphical interface. In the paper we describe the program World-Dyn?, which allows to set initial data and noise level, to set moments of parameter changes, to form the necessary visualization of results. We demonstrate the program functionality both on Forrester’s example and on our example related with crisis.

Keywords: Forrester model, world dynamics, numerical analysis.
