Population Growth, Rabbits vs. Foxes, Epidemics, and the Zombie Apocalypse: Modeling
with Compartmental Analysis
In the compartmental analysis approach to modeling, we imagine that we have one or more compartments—a tank full of water, a pond full of fish, a barrel of monkeys, a bag of cats, a box of squirrels. For each compartment, we specify a starting size, and the "flow rates" by which things can enter and leave that compartment. Then we explore what happens as time goes by: If clean water is flowing into a previously-polluted pond, how long will it take until the pollution has dropped to insignificant levels? How does the flu spread through an unvaccinated population?
