Abstract

The present status of alternative fuel vehicles, specifically electricpowered and compressed natural gas-powered vehicles is summarized. Specific advantages and disadvantages of each vehicle type, in comparison to the gasoline-powered vehicle, are reviewed. A life cycle cost model is formulated for each vehicle type. An integer linear program is derived and explained as a means of determining the optimal mix of vehicles for a command's transportation fleet. The models are tested by running several test cases using data from the Naval Postgraduate School transportation office. http://archive.org/details/modelsforconduct00gren Lieutenant, Supply Corps, United States Navy Approved for public release; distribution is unlimited.
