ABSTRACT
MAXIMIZING THE EFFICIENCY OF A SPEED RAIL FOR THE
PREPARA TION OF ALCOHOLIC BEVERAGES

Typically bartenders will arrange liquor bottles in a bar based on their own
preferences. This research project describes an alternative way to arrange the bottles on
the speed rail more efficiently. This will allow bartenders to make drinks quicker and
easier. The objective of this study is to develop some sort of heuristic using block
diagramming to make every speed rail more efficient.
For this project three different bars' speed rails were observed. The factors
considered were the top 20 selling mixed drinks at each bar and their current speed rail
setup. A generalized heuristic was used to evaluate the speed rail and make changes to
try and increase its efficiency. A block diagram of each speed rail was made to keep
track of the progress along the way.
Linear programming and a real life example were used in this project to show that
block diagramming truly made these speed rails more efficient. In the real life example
each of the top 20 selling drinks was made and timed using the existing speed rail layout
and then timed again using the new proposed layout. A quadratic assignment problem
from linear programming was used to show that the layouts found using block
diagramming were good answers.

ACKNOWLEDGEMENTS
This thesis discusses a very unique topic that has not been discussed or written
about very much. The author wishes to thank Dr. William Biles and Dr. Aldo McLean
for all of their help and support. The author also wishes to thank Dr. Gail DePuy and Dr.
Tim Hardin for making time to serve on this thesis committee. The author also wishes to
thank all of the owners and bartenders of the three establishments that are mentioned,
without them this project would not have been possible. Lastly the author would like to
thank Leslie Lee for drawing all of the figures on her computer.
