• Airline
• Beer game and the bullwhip effect
• System dynamics: Powersim
• Discrete event simulation: Simul8
• Spreadsheet: Excel
Airline
• Interactive, experiential, team-based• Accomodates large or small class size• Onsite or remote • Range of student cohorts
– Undergraduates, – Postgraduates, – Executives
• Works well for block mode student cohorts• There is a cost• www.interpretive.com

Beer game and Bullwhip effect
• Executive classes• Experiential• Demonstrates how difficult it is to control a
dynamical system– Phase lag– Oscillation– Amplification
• Requires 2 hour time slot for simulation and debrief

Powersim
• Continuous time simulation• System dynamics• Variety of applications
• Economic models• Industrial models• Tragedy of commons eg. fisheries
• Used to demonstrate examples• But takes time to learn• Site licence

dS/dt = ρA(1-S/m) – λS
Rate of change of sales = sales response to advertising x advertising x (1-sales(t) /saturation sales) – sales decay constant x sales(t)

Simul8
• Discrete event simulation– Service, manufacturing, public sector process
• call centre, high-tech manufacturing, A&E
• Software tool
• Demonstration– But takes time to develop modeling skill

Conclusion
• Simulation is an effective way to stimulate student learning
• Several approaches exist– Suit different needs/ timeslots/ student cohorts
• There can be a cost, but usually no more than a textbook
• Many strategy texts bundle in simulations• Test it before you use it, especially for a
large class
