System Zoo Z104: Exponential delay from System Zoo 1 by Hartmut Bossel

This models the progressive decline of the ability for self-reliance and the growing dependence on outside help. ​Z508 p39-42 System Zoo 3 by Hartmut Bossel. Strong outside help causes a collapse of self-help capacity. Weak outside help produces a stable combination of wellbeing and self-help capacity.

System Zoo Z109: Logistic growth with constant harvest from System Zoo 1 by Hartmut Bossel

Exercise 6 simulates a whale poplutation with a minimum reproductive capacity

System Zoo Z106: Simple population dynamics from System Zoo 1 by Hartmut Bossel

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.

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

Exploring the conditions of permanent coexistence, rather than gradual disappearance of disadvantaged competitors. ​Z506 p32-35 System Zoo 3 by Hartmut Bossel.
