Abstract: Transitioning motor vehicle to sustainable energy is of great benefits to the society in terms of reduced petroleum consumption, enhanced energy security, and reduced air pollution and Greenhouse Gas (GHG) emissions. However, the transition process is very complicate, with interdependencies among technologies, infrastructure, consumers, and policies. The complexity is further compounded by deep uncertainty in technology and consumer behavior. Thus transportation energy transition provides ample research opportunities for system modelers and industrial engineers. This seminar will present research results from two recent projects: 1) vehicle market simulation for the design and evaluation of the feebate policy and 2) charging infrastructure planning for promoting electric vehicles. For the first project, a dynamic optimization model is developed to simulate the automobile manufacturers’ behavior of improving vehicle fuel efficiency under feebate incentive and emissions standards while simultaneously considering consumers’ response to the changes of vehicle technologies and prices. The second project will show how multi-day GPS travel day can be utilized for effectively sitting charging stations in order to meet charging demand and promote electric vehicle market.
