GENERALIZED FUZZY RELATIONAL INEQUALITIES AND RELATED PROBLEMS
International Journal of General Systems, 2000Various authors investigated fuzzy relational equalities constructed on the basic of the classical max-min extension principle (Czogala, E.. Drewniak. J. and Pedrycz. W. (1982) Fuzzy Sets and Systems, 7,89-101; Sanchez, E. (1976) Information andComrol, 30, 38-48). In this contribution, generalized fuzzy relational inequalities constructed by making use

Fuzzy Relational Inequations and Equations in the Framework of Control Problems
2011The paper deals with fuzzy relational inequations and equations connected with closed fuzzy sets under a fixed fuzzy relation over the same domain. Such formulas arise in the framework of control problems. We show that fuzzy sets being solutions of these inequations and corresponding equations form a descending sequence with particular lower bounds ...

On transitive solutions of fuzzy equations, inequalities and lower approximations of fuzzy relations
Fuzzy Sets and Systems, 1995Maximal transitive solutions of relational equations and inequalities in a complete linear lattice \(L\) with universal bounds \(0\) and \(1\) and with respect to the general triangular norms are investigated. Extension to interval-valued fuzzy sets is discussed.

The quadratic programming problem with fuzzy relation inequality constraints
Computers & Industrial Engineering, 2012The quadratic programming has been widely applied to solve real world problems. The quadratic functions are often applied in the inventory management, portfolio selection, engineering design, molecular study, and economics, etc. Fuzzy relation inequalities (FRI) are important elements of fuzzy mathematics, and they have recently been widely applied in ...

Inequality relation between fuzzy numbers and its use in fuzzy optimization
Fuzzy Sets and Systems, 1985The inequality relation between two fuzzy numbers is investigated. A certain type of such a relation motivated by practical interpretation is proposed, and its correspondence with the usual lattice-type relation generated by the extended maximum and minimum operators and its possible interpretation are discussed.

Extremal solutions to fuzzy relation equations and inequalities with three unknowns
Journal of Intelligent & Fuzzy Systems, 2020A large number of studies have investigated the systems of fuzzy relation equations and inequalities, which have a much wider field of application. In this paper, we study several types of systems of fuzzy relation equations and inequalities consisting of a given family of k -ary fuzzy ...
