Sev, suggestions are made without testing. Try disturbing "Desired_Position" (note in the documentation that zero is the equilibrium position of the pendulum). I would suggest that you amend the equation for "Desired_Position" to (0 + STEP(5,5)). I chose a disturbance of five in the fifth timestep arbitrarily - set it to anything you want, experiment with it. You might also try disturbing "length_of_pendulum_rod", likewise changing the equation to (1 +
STEP(5,5)) with the same explanation as above. (For both of the above,
STEP(0,5) would leave the model in equilibrium, all other things equal.)

In the Employment Instability Model use the STEP function to disturb "Hiring_Delay" and/or "Time_to_close_Inventory_Gap".
