In the twenty-first century the sustainability of energy and transportation systems is on the
top of the political agenda in many countries around the world. Environmental impacts of human
economic activity necessitate the consideration of conflicting goals in decision making
processes to develop sustainable systems. Any sustainable development has to reconcile
conflicting economic and environmental objectives and criteria. The science of multiple
criteria decision making has a lot to offer in addressing this need. Decision making with
multiple (conflicting) criteria is the topic of research that is at the heart of the
International Society of Multiple Criteria Decision Making. This book is based on selected
papers presented at the societies 19th International Conference held at The University of
Auckland New Zealand from 7th to 12th January 2008 under the theme MCDM for Sustainable
Energy and Transportation Systems''.
