1. Simulate THAT! Jim Caristi Dept. of Math & Computer Science Valparaiso University

2. My Goal for the next 15 min. Give you a sense of the power and simplicity of using a modern simulation language to develop and interpret models very quickly

3. To do modeling well requires good tools “Good” means easy to learn easy to use powerful

4. Simulation Software Arena Simscript Stella MapleSim and Mathematica VenSim NetLogo and many others

5. Arena Discrete event and continuous modeling Commercial software from Rockwell Automation Full version lists at $1895 per license Academic version free – limited to 150 entities Download from http://www.arenasimulation.com/ http://www.arenasimulation.com/ Go to “Academic Programs”, then “Academic News”, and to the McGraw-Hill website

6. Simulate this: Barbershop Customers arrive with inter-arrival times exponentially distributed with mean 5 min. Barber cuts hair in 20 min. (normally distributed, s.d. 5 min.) Want to know how many customers in 8 hours, max and average number waiting, time in system, barber utilization

7. Simulate THIS: Bacteria on a leaf in the field grow at a temperature dependent rate The more there are, the faster they grow Leaf has maximum carrying capacity Other stuff

8. The student perspective Programming in Arena is no problem for anyone Calculus is no problem (only a very few exceptions) Statistics is a BIG problem for almost everyone

9. Some very cool student projects Zombie outbreak Grizzly bear metapopulation Dutch elm disease Volleyball scoring change Baseball Intersection or roundabout?
