1 Modeling and Simulation Dr. X

2 Topics  M/M/1 models and how they can be used  Simple Queuing Systems  Time-varying parameters  Simulation parameters when measurements are not available  Appreciation of cost/benefit tradeoffs of a simulation

3 A hospital emergency department Three queuing systems Reneging Triage process Ambulance entrance

4 Single Server Queue with Reneging

5 Priority queue

6 Tandem queues

7 Tandem queues and ambulance arrivals

8 Arrival rate

9 Mean time to renege

10 Java Modeling Tools  http://jmt.sourceforge.net/ http://jmt.sourceforge.net/  Create three tandem queues with exponential arrival and departures, simulate to find the number of customers in each queue  How would you change Queue.java to simulate three queues in tandem?
