On the Bilevel Integer Linear Fractional Programming Problem

OPSEARCH, 2001
The bilevel programming problem is a leader follower game in which two players try to maximize their own objective function over a common feasible region. In this paper we consider the bilevel programming problem in which both the objective functions are linear fractional and the variables take non-negative integral values.

A Decomposition Method for Interval Linear Fractional Programming

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1976
AbstractThe aim of the paper is to obtain a decomposition principle for maximizing a ratio of two linear functions subject to constraints in the ‘interval programming’ form. At each step of the method, two or more linear interval programming problems are to be solved, the optimal solutions of which are written explicitely with the help of Ben‐Israel ‘s

An Algorithm for Linear Fractional Functionals Programming Problems

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1977
AbstractIn this paper an algorithm is given for solving linear fractional functionals programming problems. This method permits to replace in each iteration several basic variables by an equal number of non‐basic ones so as to obtain a new basic feasible solution with the new value of the objective function which is, at least, as good as the old one ...

Extreme point linear fractional functional programming

Zeitschrift für Operations Research, 1974
This paper deals with the optimization of the ratio of two linear functions subject to a set of linear constraints with the additional restriction that the optimal solution is to be an extreme point of another convex polyhedron. In this paper, an enumerative procedure for solving such type of problems is developed.

Parametric Solution of Bicriterion Linear Fractional Programs

Operations Research, 1985
We show how certain bicriterion fractional programs can be reduced to a one parameter linear program and a series of one-dimensional maximizations. The resulting algorithm is easily implemented using the PARAROW option of MPSX, and has readily solved problems having up to 300 variables and 150 constraints.

Multicriteria linear fractional programming

2010
The object of this thesis is to study the multi-criteria linear fractional programming problems (MLFP). The characterizations of efficiency, weak efficiency and proper efficiency are derived. In the bicriteria case, the set E of all efficient solutions of (MLFP) is path-connected by a finite number of line segments and the efficient frontier F(E) can ...
