LIST OF MODELS using SimPy
==========================

:Authors:  - Tony Vignaux <Vignaux@users.sourceforge.net>,
           - Klaus Muller <Muller@users.sourceforge.net>
:SimPy version: 1.4
:Web-site: http://simpy.sourceforge.net/
:Python-Version: 2.2, 2.3

These models are some examples of SimPy use, usually developed for other purposes,
such as teaching and consulting.

Command Line input and output
------------------------------

Market.py
	Simulation of a supermarket checkout with multiple counters
	and extended Monitor objects.  Written and analysd  by
	David Mertz in an article for developerWorks (). (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)

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.  (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 are 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)


GUI Input
-----------

MM1.py  
	M/M/1 random-arrivals, exponential service time queue with GUI input.
	(MM)

GUIdemo.py
	Simulates a firework show.

bank11GUI.py
	A modification of the bank11 simulation with GUI input.

SimGUIStep.py
	A modification of the bank11 simulation with the ability to
	step between events

Plot
-----------------

bank11Plot.py
	A Modification of the bank11 simulation with graphical
	output. It plots service and waiting times
