A MULTIOBJECTIVE MODEL FOR URBAN TRANSPORT ENERGY COST AND ENVIRONMENT

摘要

This paper proposes a multiobjective approach for energy planning on transport sector, including environmental considerations. The optimization problem is formulated with two objective functions: energy cost and carbon dioxide emission. Efficient configurations for transport fleet on the planning horizon are generated by the weighted method. A trade-off curve quantifies the conflict of objectives, defining the concept of implicit carbon tax. The model variables are the road vehicle fuels: Diesel, gasoline, natural gas, electricity and alcohol. Constraints on available technologies for road transport of passenger and cargo are considered. This approach is applied to Brazilian energy scenario for road transport sector on the year 2000.
