Linear Bi-level Multi-follower Fractional Programming Problems
Wei‐Jun Chen · Journal of Wenzhou University · 2009
This paper studied on a class of minimized bi-level programming whose first level is a linear fractional program,and whose second level has K(K≥1) linear programming problems with parameters.The paper proposed a necessary and sufficient condition for the existence of solution to the problem and proved that the solution could be attained at a vertex of some polyhedral convex set.
