Exact alternative optima for nonlinear optimization problems defined with maximum component objective function constrained by the Sugeno-Weber fuzzy relational inequalities
Amin Ghodousian, Sara Zal, Minoo Ahmadi
In this paper, we study a latticized optimization problem with fuzzy relational inequality constraints where the feasible region is formed as the intersection of two inequality fuz…
A two-phase-ACO algorithm for solving nonlinear optimization problems subjected to fuzzy relational equations
Amin Ghodousian, Sara Zal
In this paper, we investigate nonlinear optimization problems whose constraints are defined as fuzzy relational equations (FRE) with max-min composition. Since the feasible solutio…
Comparison of solutions resulted from direct problems formulated as FRE
Amin Ghodousiana, Sara Zal
In this paper, we investigate direct solution of FRE and compare their results with expected real consequences. We give an applied example formulated by a FRE problem and show that…
Resolution and simplification of Dombi-fuzzy relational equations and latticized optimization programming on Dombi FREs
Amin Ghodousian, Sara Zal
In this paper, we introduce a type of latticized optimization problem whose objective function is the maximum component function and the feasible region is defined as a system of f…
A fast algorithm for the linear programming problem constrained with the Weighted power mean-Fuzzy Relational Equalities (WPM-FRE)
Amin Ghodousian, Sara Zal
In this paper, a linear programming problem is investigated in which the feasible region is formed as a special type of fuzzy relational equalities (FRE). In this type of FRE, fuzz…
