Abstract
The main objective of this study was to develop a method for enhancing the quality of tourism site selection decisions. The study proposed a spatial decision support system framework which integrates the strengths of geographic information systems (GIS) and a multiple criteria decision making (MCDM) method. The integration of G1S and MCDM into a coherent system provides users with greater utility. The system was designed in such a way that it can 1) provide capabilities to handle both the spatial and multicriteria aspects of selections; 2) guide decision makers by offering a systematic, analytic and comprehensive approach; 3) be helpful in organizing and structuring the decision; 4) help decision makers to consider and process all information relevant to the task without requiring excessive cognitive demands from them; and 5) be easy to use. Application of the system to a real world site selection problem demonstrated its usability and potential as an effective decision support tool in complex tourism site selection problems.
