Abstract :
In many infeasible linear programs it is important to construct it to a feasible problem with a minimum parameters changing corresponding to a given nonnegative vector. This paper defines a new inverse problem, called inverse feasible problem . For a given infeasible polyhedron and an n-vector X0 a minimum perturbation on the parameters can be applied and then a feasible polyhedron is concluded.
Keywords :
Inverse feasible problem , Polyhedron.
