Aims and scope of the seriesThe series 'Atlantis Computational Intelligence Systems' aims at covering state-of-theart research and development in all fields where computational intelligence is investigated and applied. The series seeks to publish monographs and edited volumes on foundations and new developments in the field of computational intelligence, including fundamental and applied research as well as work describing new, emerging technologies originating from computational intelligence research. Applied computational intelligence research may range from computational intelligence applications in the industry to research projects in the life sciences, including research in biology, physics, chemistry and the neurosciences.All books in this series are co-published with Springer.For more information on this series and our other book series, please visit our website at:www.atlantis-press.com. Da Ruan was the editor of 36 books and the author of more than 270 papers in journals and conferences. Leader of many fuzzy logic projects within nuclear science, decision systems and risk analysis, Da Ruan was a hard worker, helpful and inspirative colleague, good friend and an honest and warmhearted person. His friends and his beloved family will miss him forever.A disaster is understood as the disruption of the normal functioning of a system or community, which causes a strong impact on people, structures and environment, and goes beyond local capacity of response. In the global world of the 21 st century, a disaster that occurs anywhere of the planet affects to the whole human Society. All regions on The Earth are interconnected and any serious problem in any region will not only have direct and terrible consequences on that region, but it will also hit the social and/or economic structure of other countries. The dimension and circumstances of each disaster will determine the relief level needed (regional, national or international), but anyway they require a joint provision strategy of many regions and the concourse of International Organizations, Governmental and Non-Governmental.Disaster management implies a number of actions to be developed before disaster happens, during the disaster and after disaster takes place. Authorities at all levels as well many businesses create some sort of preventive measures and plans to reduce the disaster effects and return to normal function as quickly as possible, and from the experience learn how to improve prevention and reaction. † Prof. Da Ruan unexpectedly passed away on 31 of July 2011 after launching this book. vii viii Decision Aid Models for Disaster Management and EmergenciesResponse to natural disasters (e.g., floods, earthquakes) or technological (e.g., nuclear, chemical) is an extreme complex process that involves severe time pressure, various kind of uncertainties, and many stakeholders. Disaster management often requires several autonomous agencies to collaboratively mitigate, prepare, respond, and recover from heterogeneous and dynamic sets of hazards to Society. A...
