This paper lists in alphabetical order by the name of the first author, 532 papers dealing with
fractional programming and its applications. This covers mainly the period 2012–2015 but it …

This paper is developed to discuss the theoretical aspects of multiobjective fractional
problems under interval uncertainty. For this, we have formulated an interval multiobjective …

In this paper, we introduce the concepts of invexity, quasi-invexity and pseudo-invexity for
interval-valued functions in parametric form. Sufficient optimality conditions for a class of …

This article is devoted to obtaining necessary optimality conditions for optimization problems
with interval-valued objective and interval inequality constraints. These objective and …

Interval programming is one of main approaches treating imprecise and uncertain elements
involved in optimization problems. In this paper, an interval linear fractional bilevel program …

In this paper a problem related to portfolio optimization model is proposed to maximize the
Sharpe ratio of the portfolio with varying parameters. The Sharpe ratio model is an interval …

This article establishes a branch–bound technique to solve nonlinear convex–convex
fractional multi-objective optimization problem in the non-convex feasible region. As far as …

Запропоновано метод розв'язання задачі дрібно-нелінійної оптимізації. Показано, що
саме до такої математичної моделі зводяться численні задачі управління запасами …

This paper solves a nonlinear fractional programming problem in which the coefficients of
the objective function and constraints are interval parameters. Methodology is developed to …

In this paper, existence of the solution of a nonlinear fractional programming problem with
parameters varying in some bounds, is studied. A general nonlinear programming problem …
