lab #6 worksheet
----------------

- make a new folder for week6

- files for this week:

  w5queue1.m

- start matlab & change to the
  week 6 folder

-  KEY QUESTION to address.  what is the 
difference between the queueing systems
as employed by the banks & supermarkets?


warm-up 
-------

open "w6queue.m" in the matlab editor.
make sure that "study=1" & run it.  then 
change to "study=2" & run.

discuss the flowchart of the simulations
in the lab.


study #1 - at the bank
--------

study #2 - at the grocery
--------

- plan to make reports that discuss 
each study separately.

- you will also be budgetted extra pages
to summarize the comparison.

- approach this lab as if you were a 
consultant being asked to evaluate
and quantify the properties, advantages
and disadvantages of these two queueing
systems.

$ plan to address the key question, as
well as, design a systematic & quantitative
analysis of a second question of your 
choice.

- the code runs the simulations for 
studies 1 & 2.

- the output (graphical & otherwise) has
not been designed for you.

- the key output is the array "event_data",
each event has saved info in a row of the
array.

column 1 = eventNo = server done, or new arrival
column 2 = clock
column 3 = queue # of effected queue
column 4 = queue size of effected queue
column 5 = waiting time in queue before reaching server
column 6 = service time at server
column 7 = total people in queue

- you may add more columns for new event data.
i added col 7 when i made the code work for 
multiple queues.

- you might also save the event_data ("help save")
and write a post-processor to glean statistics
and make graphics.

- there are a few parameters that might be useful
to change.

- discussion of useful stats/graphics on the webct
is encouraged.
