Alternative Sources for

Beyond the Limits for PCs

My program describing the World3 model is being developed for use with PCs, but the development has turned out to be a big process and is taking a long time! In the meantime, here are some alternative useful resources for PCs.

The model can be obtained for Stella (a free version is available) from the IPSSR at the University of New Hampshire.
The original version of the model has been ported for use with the Vensim software and at least used to be included when you download the free Personal Learning Edition of Vensim.

Neither of the above two versions is particularly user-friendly or well documented, but they may be useful if you are willing to go to the effort to use them. You will want to obtain at least the book Dynamics of Growth in a Finite World if you want to explore the details of the model.
