Flexible querying via intuitionistic fuzzy sets
The traditional query languages used in database management systems require precise and unambiguous queries only. Fuzzy querying were introduced to relax this rigidity and allow t...

Relational Takagi-Sugeno models for rainfall-discharge modeling
In this paper, the use of fuzzy models relating rainfall to catchment discharge is investigated for the Zwalm catchment in Belgium. The models are built along the lines of Gawedaā...

On convex-concave perception based functions
Perception based function (PBF) is given by the set of rules Ri:ā€œIf X is Ti then Y is Siā€, where Ti is a linguistic term describing some fuzzy intervals Ai on the domain of re...

A measure of similarity for intuitionistic fuzzy sets
In this article we propose a new measure of similarity for intuitionistic fuzzy sets. The proposed measure takes into account not only a pure distance between elements but measure...

Fusion with quantitative weights
Based of the strong idempotency of aggregation operators, quantitative weights are incorporated into the fusion process. Our general method is compared with some previous speciļ¬...

Analysis of multi-product break-even with uncertain information
We revise the classic methodology to find the multi-product break-even point. In the current paper we propose a solution to the problem under uncertainty conditions, based on DurĆ...

Generalized negations and intuitionistic fuzzy sets - a criticism to a widely used terminology
Intuitionistic Fuzzy Sets Theory is based on a wrong nominalistic (terminological) assumption. It is deļ¬ned as ā€œintuitionisticā€ a negation which does not satisfy usual prope...

Decision-theoretic approaches in fuzzy rule generation for diagnosis and fault detection problems
A typical task in technical fault detection or medical diagnosis problems is to discriminate normal behavior from one or more types of abnormal behavior by means of different meas...
