In this paper, we introduce new concepts of e-weak efficient solutions and e-efficient solutions for a nonconvex multiobjective fractional programming problem involving n-set functions. Using an e-parametric approach and a new theorem of alternative for nonconvex n-set functions, some necessary and sufficient conditions for e-approximate solutions are derived.
