I am looking for some pc based simulation software.  I need to figure out
how many spare parts to purchase to keep an operation going.  For example,
I have a process machine that uses a mold.  Normally,  the mold can be
used for 3 days assuming nothing bad happens.  After 3 days,  it must go
to a machine shop for a minimum of 7 days for refurbishing.  Most of
the time,  the molds do not get to the 3 day point before an accident
occurs.  The accident sometimes requires a 7 day refurbishment or if
I'm lucky,  only a few hour clean up job.  To complicate matters,  there
are two sizes of molds dependant on the product mix that has to be run.
 
What I would like to do is to simulate this for various accident scenerios,
product mix runs, etc.  I have a lot more equipment that has to be
simulated in this way to project the need for spare parts in advance.  We
haven't started up yet.
 
Any help in pointing me in the right direction would be appreciated
Thanks,
Jim
