The method used for evaluating the flood risk management policy decision problem in the Upper Tisza Basin (UTB) is based on the Delta method (Danielson 98). It has been further developed and extended to handle a problem model in which several stakeholders’ outcomes can be handled on a per consequence basis. Thus, it is a multicriteria extension to the basic(More)
The study of complex phenomena, such as the interplay between human and natural systems, requires models. To allow for an orderly study of the effects of individual actions the model must comprise different scales of granularity, individuals and aggregates. In a joint research project between IIASA (Austria), DSV (Sweden) and the Hungarian Academy of(More)
My work within a research project studying flood-risk management in Hungary is described, with special attention on loss-spreading instruments, mainly insurance. I argue that computer simulation tools are useful in catastrophe policy making. Computer simulation provides a method for estimating the consequences of different potential policy strategies. In(More)
A geographically explicit flood simulation model was designed and implemented as a tool for policy making support, illustrated here with two simple flood management strategies pertaining to the Upper Tisza area in Hungary. The model integrates aspects of the geographical, hydrological, economical, land use, and social context. The perspectives of different(More)
The Hungarian government is experiencing escalating costs for flood mitigation measures and for economical compensation to victims. In a joint research project between the International Institute of Applied System Analysis (IIASA) in Austria, Computer and System Science Department (DSV) in Sweden, and the Hungarian Academy of Science, the flooding problem(More)
A simulation model called VirSim was developed to aid policy making in Sweden. The model simulates the spread of pandemic influenza, using real population data on a national and regional level. Swedish authorities wanted a model that was both quick to run and to implement as a complement to the existing model MicroSim. The possibility to interactively(More)
