Reducing t-norms and augmenting t-conorms

International Journal of General Systems, 2002
We study here the behavior of the t-norms at the point (1/2, 1/2). We indicate why this point can be considered as significant in the specification of t-norms. Then, we suggest that the image of this point can be used to classify the t-norms. We consider some usual examples. We also study the case of parameterized t-norms.

Nestings of T–Conorms

2009
This paper deals with a new method to construct a new t---conorm from two previous ones, by what we call a nesting procedure. After some general considerations about this method, we study those t---conorms obtained by nesting appropriate t---conorms in the basic maximum, drastic and Lukasiewicz t---conorms.

EXTREMAL k-LIPSCHITZ t-CONORMS

International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 2006
Class of k-Lipschitz t-conorms is shown to have no strongest element for k > 1. Pointwise supremum of the class of k-Lipschitz t-conorms is introduced and the best approximation of this supremum by k-Lipschitz t-conorm is constructed.

A note on moderate growth of t-conorms

Fuzzy Sets and Systems, 2001
Given a t-conorm \(S\) on [0,1], \(S\) is said to exhibit moderate growth if for all \( a> b \) we have \[ S(v,a) - S(v,b) \geq S(u,a) - S(u,v), \tag{1} \] whenever \( u > v \). Using results of C. Kimberling, R. Moynihan and A. Sklar, the author explains the relation between moderate growth an copulas, i.e., \(S\) is continuous and satisfies (1) if ...

Propositional Belief Merging with T-conorms

2017
We analyze in this paper the impact of introducing fuzzy T-conorm operators in the area of belief merging. There are mainly two subclasses of merging operators: the utilitarian and the egalitarian ones. We prove that a T-conorm merging operator can be included in the subtype of egalitarian operators.

Choosing t-Norms and t-Conorms for Fuzzy Controllers

Fourth International Conference on Fuzzy Systems and Knowledge Discovery (FSKD 2007), 2007
The choice of t-norms and the dual t-conorms should, in principle, play a key role in the operation of a fuzzy control system, particularly the output of the system. The t-norms are expressed differently and appear to have different properties. We show analytically, using a zero-order Takagi-Sugeno controller the regions where the choice of a t-norm is
