Modeling and Simulation Dr. X

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

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

Single Server Queue with Reneging

Priority queue

Tandem queues

Tandem queues and ambulance arrivals

Arrival rate

Mean time to renege

Java Modeling Tools   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?
