Fuzzy simulation and its application to environmental prediction

In model building for urban environment, the difficulty of structure identification and the lack of homogeneity in data is often encountered. To cope with these problems, the authors are developing a modeling support system to utilize objective information and subjective knowledge effectively. In this paper they propose a fuzzy modeling technique with a visual and stepwise clustering method, and a fuzzy simulation technique for reasonable scenario input and interpretation of the model behavior. The authors present an application of the proposed techniques to an urban environmental problem. [In Japanese.]
