Multiple Criteria Analysis for Flood Vulnerable Areas Track: Environmental Management Author(s): Guler Yalcin, Zuhal Akyurek Cell-based Multicriteria Evaluation (MCE) methods are used to analyze areas vulnerable to flooding. GIS is integrated with Multicriteria Decision Analysis (MCDA). In ArcView 8.2 all data are stored and the criterion values are generated for all criteria that are seen as map layers. The criterion maps are converted into grids and the mathematical processes are applied to the criteria with MapCalculater. Ranking Method, which is used to rank every criterion under consideration in the order of the decision maker's preferences, and Pairwise Comparison Method (PCM), which is designed as a user interface to calculate the weights from input preferences with Visual Basic for Applications (VBA) program embedded in ArcGIS 8.2, are used. At the end of the application, the composite maps are created using Boolean Approach, Ranking Method, PCM, and Ordered Weighted Averaging (OWA) Method, and fuzzy concept on standardization of the criterion values are compared.
