In this talk I present an integrated workflow for a generative-evaluative spatial decision support approach. The workflow corresponds to classical decision support model of intelligence - design - choice. A spatially adaptive multiple objective genetic algorithm (MOGA) is utilized to generate robust trade-off options. Then, exploratory multiple criteria decision analysis techniques are deployed to identify salient solutions. This is followed by further evaluation of the selected solutions using ancillary spatial criteria. The tri-phase, generative-evaluative workflow is then applied for a problem of hazard management, in which the decision task involves selecting a geographic configuration of an environmental sensor network for radioactivity monitoring in a trans-border region including the state of Lower Saxony in Germany and the Netherlands.
Dr Piotr Jankowski is a professor of Geography and co-director of Center for Earth Systems Analysis & Research at San Diego State University. Before coming to San Diego State University he held faculty appointments in Geography at the University of Idaho and in Geoinformatics at Westfaelische Wilhelms Universitaet in Muenster, Germany. More recently he held the Walton Professorship of GIScience (Visiting) of the Science Foundation of Ireland at College University, Dublin and several Fullbright awards from the United States to Poland and Germany. Professor Jankowski is on the editorial boards of leading international journals in the field of GIScience including Transactions in GIS and the Journal of Geographical Systems. His research focuses on Spatial Decision Support Systems, Participatory Geographic Information Systems, Spatial Optimization and Visual Analytics Methods. He has published extensively in leading Geography and GIScience journals and has been the PI and Co-PI on a number of research projects funded by NSF, NASA, and various state agencies. His new book "GIS for Urban and Regional Environments: A Spatial Decision Support Approach", co-authored with Timothy Nyerges from University of Washington was recently published by Guilford Press. He is currently a Visiting William Evans Fellow at the School of Surveying.
