In this paper by error bound approach, we establish some equivalent single level formulation of the generalized bilevel programming problem. The necessary optimality condition of Kuhn-Tucker type are then given by using nonsmooth analysis.engeneralized bilevel programming problemsvariational inequalityerror boundnecessary optimality conditionnonsmooth analysisTechnical Report
