Dear Jim,
there exist several systems for modelling and simulation of similar systems
as yours. I think, you need not program it in a simulation language but use
more compact approach.
My colleague and myself have designed such a system under spreadsheet system
EXCEL 5 (for Windows). You can have some pre-beta version. (You should have
at least 386 8 Mb machine with Windows and Excel 5.)
I should appreciate if you would test our system by solving your problem. For
it, send me your normal address and I will send you diskete and some draft
manual. At the same time, you can send me by e-mail more detailed
description and parameters of your problem and I can try prepare it as an
example for you.
There is a little bit time problem. For next two weeks (till 19 March) I have
my holidays, but afterwards I can do things very quickly. I will read
messages on Friday 3 March and Friday 10 March and then on Monday 20 March.
Sincerely yours
               Marcel Jirina
