Abstract: The authors' focus was to determine the usefulness of the fuzzy set approach in evaluating the urban residential environment, compared with the crisp (or Boolean) approach. Particular emphasis was placed upon the comparison of evaluation results produced by the two methods within a geographic information system (GIS). This comparison highlighted the advantages of the GIS-fuzzy set approach as follows. First, it was revealed that the fuzzy set approach could reduce excessive abstraction or exaggeration in environmental phenomena. Hence, without the loss of valuable information, more accurate decisionmaking can be rendered. Second, by integrating membership functions into GIS, greater efficiency of the entire evaluation process was achieved.
