We can cause an overshoot and collapse structure to oscillate if we provide it with a resource that can renew itself quickly. The system is one of equilibrium until it is shocked which causes the system to oscillate.
Hints:
- Set the DT to 1 and change the simulation method to either of the two Runge-Kutta methods.
- Make sure the inflow and outflow of the stock values are the same.
- Do the same for the resource inflow and outflow.
- Set the simulation of a longer run time...say about 100 time steps.
To create the model:
stock = 50
outflow 1 = 10
inflow 1 = resource * conversion 1
resource = 100
inflow 2 = 20
outflow 2 = stock * conversion 2
conversion 2 = .4
conversion 1 = .1*step(1,1)
