On the ratio of fuzzy numbers – exact membership function computation and applications to decision making

Technological and Economic Development of Economy, 2015
In the present paper, we propose a new approach to solving the full fuzzy linear fractional programming problem. By this approach, we provide a tool for making good decisions in certain problems in which the goals may be modelled by linear fractional ...

A new model for solving fuzzy linear fractional programming problem with ranking function

Journal of Applied Research on Industrial Engineering, 2017
In this paper, we studied fuzzy linear fractional programming (FLFP) problems with trapezoidal fuzzy numbers where the objective functions are fuzzy numbers and the constraints are real numbers.

Energy efficiency maximization in MIMO links aided by metasurfaces with global reflection constraints

EURASIP Journal on Advances in Signal Processing
This work develops two radio resource allocation algorithms to optimize the energy efficiency of a multiple-input multiple-output (MIMO) communication system where a metasurface is deployed near the transmit antenna array to create a reconfigurable ...

Fractional programming in cooperative games [PDF]

, 2013
Cooperation of individuals or institutions is often coupled with benefits that can be regarded as the monetary worth or outcome of the cooperation. Therefore, the problem naturally arises how to allocate the total outcome among institutions or individuals in a fair way. Such allocation problems are studied within cooperative game theory. A general idea

Convexification techniques for fractional programs

Mathematical Programming
This paper develops a correspondence relating convex hulls of fractional functions with those of polynomial functions over the same domain. Using this result, we develop a number of new reformulations and relaxations for fractional programming problems.

The multiobjective transportation fractional programming model [PDF]

Computer Science Journal of Moldova, 2005
In this paper the multiobjective transportation problem of linear-fractional type with one nonlinear time constraint criterion is investigated. Particularly, the case of the identical denominators is studied. The concrete procedure to find the set of all

An Investigation on the Fractional Transportation Problem via Weibull Distribution

Transactions on Fuzzy Sets and Systems
In this work, multi-objective fractional stochastic solid transportation problem uncertainties are represented using the Weibull distribution. This transformation converts the multi-objective fractional stochastic solid transportation problem into a goal
