ANN: SimPy 1.4.1 discrete event simulation package
It is our pleasure to announce the release of SimPy 1.4.1, a maintenance release of SimPy 1.4.
It can be downloaded via the SimPy homepage http://simpy.sourceforge.net.
What is new? ------------ This release makes no changes to the SimPy API. It repairs two bugs and improves on the unit test coverage:
Resource -------- - To repair a bug with monitoring the activeQ of a Resource instance, method _release in class Resource has been changed in modules Simulation.py, SimulationRT.py, SimulationTrace.py and SimulationStep.py
testSimpy.py ------------ - This unit test module has been enhanced with a unit test for monitored Resources.
cellphone.py ------------ - This example had a programming error and has been corrected. File names ---------- - All file names in the source distributions have been made “Unix-friendly” by changing file names containing blanks.
What is SimPy? -------------- SimPy is a process-based discrete-event simulation language package implemented in Python and released under the GNU GPL.
It provides the modeller with building blocks for simulation models. These include processes, for active components like customers, messages, and vehicles, and resources, for passive components that form limited capacity congestion points like servers, checkout counters, and tunnels. It also provides monitor variables to aid in gathering statistics.
SimPy has a Tkinter-based GUI and a plotting package.
SimPy comes with extensive reference and tutorial documentation.
SimPy is in use in universities, research institutes and industry.
