Tim Hardm II ABSTRACT MAXIMIZING THE EFFICIENCY OF A SPEED RAIL FOR THE PREPARA TION OF ALCOHOLIC BEVERAGES Ashley Riley July 16, 2010 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. iii ------------------------------------------------------- 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.
