| Find a queing theory expert (is there a MATHS notesfile?) or a serious
expert in factory floor operations design.
Or a maths/simulation package with a queueing option and a good manual.
(Simscript? Matlab??).
Or a manufacturing simulation package (e.g. Seewhy from AT+T Istel -
serious money required unless there's now an el-cheapo PC version).
Turn the way-back dial three years back and ask the MIACT (oh, shucks,
they've almost all gone...).

| Hey Nick, do you want a copy of M J Moroney's "Facts from Figures"? - best remembered quote -
Pat: "Rome wasn't built in a day"
Mick: "but oi wasn't on dat job"
Seriously, I wouldn't calculate, I'd simulate. It's easy to generate random values of the times
once you have their distributions. Then you just let it run for a while and look at the results.

| I think you're missing some information; what's the distrubution of the
PROCESS and UNLOAD times?
This is pretty standard queueing theory stuff, unfortunately I haven't
done queueing theory since I was in grad school hundreds of years ago..

| The POLYCENTER Capacity Planner group has a number of people with a lot of
knowledge in queuing theory. They may be able to provide consultancy in
this endeavor. Contact Melur Raghuraman DTN 381-1373 (DISCOS::RAGHU).

the math notes files is at
RUSURE::NOTES1:[NOTES$LIBRARY]MATH.NOTE;7
there is a fair amount of statistical knowledge there.
sometimes an analytic solution is possible. often it is not.
even when an analytic solution is possible, simulation is often
the best way to go. simulation makes it easy to evaluate the
sensitivity to small changes in the assumptions.

| A recent issue of Dr. Dobb's Journal (no older than November 96)
covered the Denver Airport baggage-handling fiasco. The article
included code used for simulating the baggage flow. Might be worth a
look.
