Church growth models have been developed with system dynamics and implemented in "Stella" produced by ISEE Systems. Some of the models have web-based versions, hosted by Forio Simulate, enabling anyone to experiment with the models using intuitive controls. The Stella model is available from the same site.
Models - Technical DetailsChurch Growth models have all been developed using system dynamics, although some did originate as mathematical models using systems of differential equations. The standard method is to analyse and test the models using mathematics, simulation and system dynamics techniques. The models have been implemented in simulation software: Stella, Vensim, Berkeley-Madonna, MathCad and in the author's own programs written in the Ada programming language.
