Linear Fractional and Bicriteria Linear Fractional Programs

In this paper we will restate the sequential methods suggested by the Authors for solving a linear fractional problem for any feasible region using the concept of optimal level solutions. By following this approach, sequential methods for solving the bicriteria linear fractional problem are proposed; these methods generate the set E of all efficient points and, at the same time, point out that E is arcwise-connected when at least one of the objective functions is linear.
