Test your understanding of system dynamics with 5 practice questions.
Practice Questions
Question 1
In a system dynamics model, which of the following best represents a situation where a stock's value is influenced by its own past value, creating a self-perpetuating cycle?
Question 2
Consider a system dynamics model for a company's sales. If 'Advertising Spend' increases 'Brand Awareness', which in turn increases 'Sales', and 'Sales' then generates more 'Advertising Spend', what type of feedback loop is primarily at play?
Question 3
When analyzing the long-term behavior of a system using system dynamics models, what is the primary reason for incorporating 'delays' in the model?
Question 4
A system dynamics model of a fishery includes 'Fish Stock' as a stock, 'Birth Rate' as an inflow, and 'Harvest Rate' as an outflow. If the 'Birth Rate' is proportional to the current 'Fish Stock' (with a constant of proportionality $k_b = 0.1$ fish/fish/year) and the 'Harvest Rate' is constant at $500$ fish/year. If the initial 'Fish Stock' is $10,000$ fish, what is the net change in 'Fish Stock' after $1$ year?
Question 5
Which of the following statements most accurately describes the relationship between 'stocks' and 'flows' in system dynamics?
