A New Approach for Comparing Fuzzy Objectsmeasures are necessary to find objects which are close to other given fuzzy objects or used in a user vague query. Such similarity measures could be also utilized in fuzzy database or even classical relational database modeling. In this paper we propose a new family of similarity measures in order t

This paper deals with querying such null values, and more specifically null values representing inapplicable information, and tries to come up with semantically richer, but still correct, query answers in the presence of null val

Aggregation of Partly Inconsistent Preference Information preference information required for the method described in this paper is significantly less complex and is simply defined on the decision set. For every decision goal the preference of the decision alternatives for this goal is defined upon the set of decision alternatives as a linear ranking of t
