Abstract: Optimal conditions and duality are the most important parts of the theory for mathematical programming,Reddy.L.V.and Mukhejee.R.N.discussed the sufficiency and the duality of Mond Weir type on the fractional programming with generalized invexity in Ref.(1),but the main result is incorrect,In this paper.we correct one error in Ref.(1),and discuss the multiobjective fractional programming with generalized invexity,obtain Some sufficient conditions,introduce one type of dual model,and prove the corresponding theorems of weak duality and strong duality.
