Journal of Inequalities and Applications, 2019 A new class of (not necessarily differentiable) multiobjective fractional programming problems with E-differentiable functions is considered. The so-called parametric E-Karush–Kuhn–Tucker necessary optimality conditions and, under E-convexity hypotheses,

An Exact Method for Fractional Goal Programming [PDF]
Journal of Global Optimization, 2004 Goal Programming with fractional objectives can be reduced to mathematical programming with a linear objective under linear and quadratic constraints, thus optimal solutions can be obtained by using existing Global Optimization techniques. However, only heuristic procedures are suggested in the literature on the field.

Duality and Sensitivity Analysis for Fractional Programs [PDF]
Operations Research, 1976 In this paper we consider algorithms, duality and sensitivity analysis for optimization problems, called fractional, whose objective function is the ratio of two real-valued functions. We discuss a procedure suggested by Dinkelbach for solving the problem, its relation to certain approaches via variable transformations, and a variant of the procedure ...

Sensitivity analysis in piecewise linear fractional programming problem with non-degenerate optimal solution [PDF]
Opuscula Mathematica, 2009 In this paper, we study how changes in the coefficients of objective function and the right-hand-side vector of constraints of the piecewise linear fractional programming problems affect the non-degenerate optimal solution.

A dynamic programming approach to adaptive fractionation [PDF]
Physics in Medicine and Biology, 2012 We conduct a theoretical study of various solution methods for the adaptive fractionation problem. The two messages of this paper are: (i) dynamic programming (DP) is a useful framework for adaptive radiation therapy, particularly adaptive fractionation, because it allows us to assess how close to optimal different methods are, and (ii) heuristic ...

Generalized Heptagonal Membership Function for Fully Fuzzy Linear Fractional Programming Problems
Ibn Al-Haitham Journal for Pure and Applied SciencesIdentifying the optimum solution that satisfies the restrictions and maximizes or minimizes the objective function is the aim of fully fuzzy fractional programming (FFFLP). Due to the inclusion of both fuzzy parameters and fractional variables, this

Fractional CCP: A Fuzzy Goal Programming Approach
International Journal of Industrial Engineering and Production Research, 2014 It is the purpose of this article to introduce a linear approximation technique for solving a fractional chance constrained programming (CC) problem. For this purpose, a fuzzy goal programming model of the equivalent deterministic form of the fractional ...
