Fisheries model from Hartmut Bossel "System Zoo 3 Simulation Models: Climate Ecosystems, Resources"

An exploration of interactions among 'fuzzy' qualitative concepts that interact to produce either tolerance or violent conflict. ​Z509 p43-49 System Zoo 3 by Hartmut Bossel.

Based on the Market and Price simulation model in System Zoo 3.

System Zoo Z107: Infection dynamics from System Zoo 1 by Hartmut Bossel

Adapted from Hartmut Bossel's "System Zoo 3 Simulation Models, Economy, Society, Development."

​Population model where the population is summarized in four age groups (children, parents, older people, old people). Used as a base population model for dealing with issues such as employment, care for the elderly, pensions dynamics, etc.

This is my attempt at the problem, not necessarily correct!

Systems Zoo model Z308 Forest Dynamics (Bossel, 2007)

Based on the Market and Price simulation model in System Zoo 3, Z504. In this model the profit calculations were not realistic. They were based on the per unit profit, which does not take items not sold into account. Also the model was not very clear on profit since it was included in the total production costs and consequently in the unit costs and subsequently profit was calculated by subtracting unit costs of the market price. Thus profit had a double layer which does not make the model better accessible. I have tried to remedy both in this simplified version.
