We study a nonlinear multiple objective fractional programming with inequalityconstraints where each component of functions occurring in theproblem is considered semidifferentiable along its own direction instead ofthe same direction. New Fritz John type necessary and Karush-Kuhn-Tuckertype necessary and sufficient efficiency conditions are obtained for a feasiblepoint to be weakly efficient or efficient. Furthermore, a general Mond-Weirdual is formulated and weak and strong duality results are proved usingconcepts of generalized semilocally V-type I-preinvex functions. This contributionextends earlier results of Preda(2003), Mishra et al. (2005), Niculescu(2007), and Mishra and Rautela (2009), and generalizes results obtained in the literature onthis topic
