FDS+EVAC: Herding Behavior and Exit Selection

Report Date: January 2011

Exit selection during an emergency evacuation depends partly on individual behavior. In this project, three individual behavior types are considered: conservative, active, and herding. The distribution of these individual behavior types will vary depending on venue, and these distribution differences will effect behavior and should be accounted for in evacuation models. The three behavior types are implemented into the FDS+EVAC simulation model to test the effects of various group compositions on evacuation. The details of the testing and results were published in the International Association for Fire Safety Science symposium proceedings.

  • International Association for Fire Safety Science

    IAFSS was founded with the primary objective of encouraging research into the science of preventing and mitigating the adverse effects of fires and of providing a forum for presenting the results of such research.The International Association for Fire Safety Science perceives its role to lie in the scientific bases for achieving progress in unsolved fire problems. It will seek cooperation with other organizations, be they concerned with application or with the sciences that are fundamental to our interests in fire. It will seek to promote high standards, to encourage and stimulate scientists to address fire problems, to provide the necessary scientific foundations and means to facilitate applications aimed at reducing life and property loss. Since its inaugural meeting, the IAFSS has grown to more than four hundred members. Current members come from Australia, Austria, Belgium, Brazil, Canada, China, Denmark, Germany, Finland, France, Holland, Hong Kong, India, Ireland, Italy, Japan, Korea, Luxembourg, Netherlands, New Zealand, Norway, Russia, Spain, Sweden, Switzerland, Taiwan, United Kingdom and United States of America. The Association is legally established as a charitable organization in England and Wales.

  • Aalto University, Systems Analysis Laboratory

    Systems Analysis Laboratory was established in 1984 within the professorship of applied mathematics in the Helsinki University of Technology. Now we are part of the new Aalto University. The founder and director of the laboratory is Professor Raimo P. Hämäläinen. Our other professors are Harri Ehtamo, Ahti Salo, Kai Virtanen and Enrico Bartolini. Professor Esa Saarinen from the Department of Industrial Engineering and Management is a co-director of our Systems Intelligence Group.

    The research interests of the laboratory cover the area of systems science comprehensively ranging from the mathematical theories and algorithms of optimization, control and decision making to the practical interactive computer modeling and decision support systems and risk and technology assessment. The focus of the applications is in complex energy, production and environmental systems. The problems are analyzed with a balanced engineering-economic systems approach. We also have a long tradition in biological modelling. Currently we have a growing effort in studying systems intelligence and applied philosophy in human organizations.

    As an university institution the laboratory is unique in Finland. It is responsible for the undergraduate major of Systems sciences and for the graduate major of Systems and operations research in the Engineering Physics and Mathematics programme. We also give general courses in opimization, statistics and modeling. The laboratory is in charge of the national Doctoral Education Network in Systems Analysis, Decision Making, and Risk Management.
