Apply the population models to real countrys or regions. Make predictions based on historical data and check them against current data. Adapt the SIR model to your favorite disease, or possibly make it a more realistic model for measles. By the way, SIR is called a 3-compartment model for the three groups of people in the model. Lead in human bodies has a 3-compartment model.
Lead is in the blood stream, bones and tissues.
Investigate the effects of the lead as it enters the blood stream and how various treatments might affect the levels in the 3 compartments. Write your favorite problem as a linear programming problem. This includes transportation problems as outlined in Appendix 2. Game Theory is modeled later in the book, but is a nice model for many problems. This project will be graded on a 100 point scale using posted grading criteria .
