These models are some examples using the SimPy simulation system.

MM1.py
M/M/1 random-arrivals, exponential service time queue with GUI input. (MM))
MMC.py
M/M/c (multiple server queue model. This demonstrates both the multiple capacity Resource class and the use of tally and accum in the Monitor class. Random arrivals, exponential service-times. (TV)
Market.py
Simulation of a supermarket checkout with multiple counters and extended Monitor objects. Written and analysed by David Mertz in an article for developerWorks (). (MM)
SimPy_worker_extend.py
Factory making widgets with queues for machines. (MM)
airport.py
A simple model of an airport with service with a single runway. Times are deterministic and statistics are not (yet) gathered. (TV)
bcc.py
Detemine the probability of rejection of random arrivals to a 2-server system with different service-time distributions. No queues allowed, blocked customers are rejected (BCC). Distributions ae Erlang, exponential, and hyperexponential. The theoretical probability is also calculated. (TV)
cellphone.py
Simulation of a cellphone cell with blocking (that is BCC discipline). The program simulates the operation for 10 "hours" and measures the mean and variance of the total time blockedr and the number of times blocking occur in each hour. An observational gap occurs between the observation hours to make each hour's measurement independent. (TV)
centralserver.py
Simulates a primitive central-server model with a single CPU and a single disk. A fixed number of users send "jobs" to the system which are processed and sent back to the user who then thinks for a time before sending a job back. This system can be solved analytically. (TV)
jacksonnetwork.py
Simulation of a Jackson network with 3 nodes, exponential service times and probability switching. The simulation measures the delay for jobs moving through the system. (TV)
lemmings.py
A simple M/M/1 Lemming model. (TV)
shortestPath_SimPy.py
A fun example of using SimPy for non-queuing work. It simulates a searcher through a graph, seeking the shortest path. (KGM)
Machineshop.py
An example of the use of the 'interrupt()' method introduced in SimPy 1.2. It simulates a workshop with n machines which break down and one or more repairmen which have to repair them. (KGM)
CellularAutomata.py
A simple simulation of two-dimensional cellular automata. Does the game of Life. (KGM)
bank11GUI.py
The Bank11 model from the Bank Tutorial with a SimGUI frontend. (KGM)
bank11Plot.py
The Bank11 model from the Bank Tutorial with a SimPlot plotting output. (KGM)
testSimplePlot.py
A simple test/demo of some of the SimPlot plotting capabilities. (KGM)
SimGUIStep.py
A version of the Bank11 model with a GUI (using SimGUI) which allows executing the simulation either even-by-event or in one go. This makes use of the SimulationStep module new in version 1.4. (KGM)
StepExample.py
A very basic model demonstrating command-line control over event-by-event model execution, using SimulationStep. (KGM)
