The emphasis on cleaner air and energy independence has prompted federal legislation to promote the use of Alternative Fuel Technologies (AFT) during the past decade. As a result, the automotive industry has been searching for solutions to meet the energy challenge in the United States. Transportation is continues to consume increasingly large amounts of fuel and U.S. dependence on foreign oil has grown to almost 60%. The gasoline shortages during the 70s and the effects of the Persian Gulf War also emphasize the excessive dependence on foreign oil. Vehicle manufacturers throughout the world are busily exploring types of vehicles that emit zero or near zero exhaust emissions. Technologies range from refining the internal combustion engine to electric systems powered by fuel cells. Alternative fuels that show potential to future transportation includes: propane (LPG), natural gas (CNG), bio-diesel, hydrogen(FC) and electricity In addition, the consumer demand is also shifting to alternative fuel technologies (AFTs) but governments and Industry have done little to aid consumers in making a decision to choose among the alternative type of fuel technologies used in vehicles that are available today or perhaps projected to be released in the near future. This project covers the Evaluation and Selection Process for the Best Alternative Fuel Technology used in Vehicles (AFT) for US Consumers. The results include a Hierarchical Decision Model (HDM) using pair wise comparison that selects the best Alternative Fuel technology used in vehicles with respect to selection criteria’s and expert panel judgments. Finally, the result is summarized and the model limitation is identified to set the stage for future studies.
