Examples • Optimization (Solver) • Decision Trees (Precision Tree) • Statistics and Data Mining • Simulation • Formulas (@Risk) • Processes (SimQuick)
Idea of Simulation • Goal: Evaluate a strategy. • Examples of strategies: • Investments • Games • Process improvement • Technique: Build a model in the computer and test the strategy on it.
A company that has implemented this idea on a big scale: www.financialengines.com
Example: Waiting at a bank • Customers arrive every 2 minutes (on average; exp. dist.).
Customers enter a single line. • There is a single teller; service takes 2.4 minutes on average (normal dist. with a st. dev. of .5 minutes).
Process improvement ideas • Add a second teller. • Speed up the single teller with some automation.
Other applications of simulation • Queueing systems • Call centers • Logistics systems • Computer networks • Financial analysis • Health care systems
Simulation with animation • An on-line example
