Fuzzy relational algebra for possibility-distribution-fuzzy-relational model of fuzzy data

  title={Fuzzy relational algebra for possibility-distribution-fuzzy-relational model of fuzzy data},
  author={Motohide Umano and Satoru Fukami},
  journal={Journal of Intelligent Information Systems},
In the real world, there exist a lot of fuzzy data which cannot or need not be precisely defined. We distinguish two types of fuzziness: one in an attribute value itself and the other in an association of them. For such fuzzy data, we propose a possibility-distribution-fuzzy-relational model, in which fuzzy data are represented by fuzzy relations whose grades of membership and attribute values are possibility distributions. In this model, the former fuzziness is represented by a possibility… CONTINUE READING
