Re: Simpy 2.3.1

Which version of Python do you have? SimPy 2.3 requires at least Python 2.6.

cheers,

It's part of a collection of  examples that are part of the SimPy
distribution, but not part of any manual.  It doesn't get tested as
it's output is mostly SimPlot.

It's not yet python 3 compliant either. (we need to go thru this
directory.) Runs under python 2.6.

All of my problems have been identified and solved. Although I had installed
the latest Python and Simpy, I had an earlier version of Python (2.5) on the
computer, which was the one being used! Replacing this with the latest
version and reinstalling Simpy enabled me to get back to a working, stable
system.
Many thanks for your replies

Re: Hospital patient flow questions

Hi Steven,

Thank you for your reply.

Do you have an example for your answer to question 1? It seems if I separate the files I will get a "Activating
function which is not a generator (contains no 'yield')" error.

For your answer in question 2, can multiple generators share the same PEM or share parts of the same PEM? For
example patient 1 arrives via public transport, goes through triage, then nurse assessment; patient 2
arrives via car, goes through the SAME triage, then straight to X-ray room.

Regards,

Kelong

Hi Cong,

For question 1:
Your classes that inherit from SimPy.Simulation.Process need to have
at least one function with a "yield" statement. Check your code - I
suspect this is where the error is coming from.

For question 2:
There are probably plenty of ways to do it, but I would model it this way:
1. Your patients are objects with attributes that define what will
happen to them when they go through the hospital processes
2. You will have several Stores that hold the Patient objects (eg.
waiting room, x-ray waiting line, etc)
3. Your generators simply create Patient objects at different rates,
with different attributes (e.g a patient arriving by ambulance may
have a higher likelihood of needing an x-ray). Once the Patient object
is created, they will be put into the WaitingRoom store.
4. Your Triage process has a single PEM which defines what happens to
the patient (ie. what Store they will be placed into next). This
should be based on attributes of the Patient object (eg. if
patient.broken_arm==True: yield put,self,XRayWaitLine,[patient]).
5. You then have other hospital processes (eg. X-Ray) that take

Re: simpy installation error (python 3.2)

Hi,

it looks like you are using SimPy 2.3. The bug is fixed in 2.3.1.

I recommend you to install PIP (a package manager for python: http://pypi.python.org/pypi/pip)
and install SimPy with it:

   pip install -U simpy

Cheers,
Stefan

Re: Citing SimPy in a scientific article

Hi Linus,

afaik, there are no recent papers or presentations you could cite. So if you just want to cite SimPy as a
library, you could simply refer to http://simpy.sourceforge.net/ with a misc/booklet/webpage entry.

But maybe Tony has a better idea?

Stefan
