Toyota Motor Energy Analysis and Modeling

Abstract

The automobile manufacturing industry in the U.S. uses over 800 trillion British Thermal Units (Btus) of energy and spends about $3.6 billion on it each year. As a leading automobile manufacturing corporation, our client Toyota Motor Engineering & Manufacturing North America, Inc. (Toyota) seeks opportunities to improve their accuracy in predicting manufacture energy use. With a better understanding of future energy use, Toyota will be able to identify energy efficiency opportunities and improve the overall budgeting accuracy at corporate level. To accomplish this goal, this project uses five years of historical energy consumption data to test existing energy models and identify possible improvements that can be done on a process and plant level. The products of this study include revised energy models for manufacture energy use and administrative energy use for both electricity and total energy consumption. Toyota could use our models as a reliable reference to predict future energy performance.
