On the basis of arcwise connected convex functions and ( p ,  r ) −η - invex functions, we established H b  –( p, r ) –η- invex functions. Based on the generalized invex assumption of new functions, the solutions of a class of multiobjective fractional programming problems are studied, and the sufficient optimality condition for the feasible solutions of multiobjective fractional programming problems to be efficient solutions are established and proved.
