Abstract: A new interval CW-order relation is introduced in this paper. By the CW-order relation, the interval valued pre-invex, pseudo-invex and quasi-invex functions are introduced, then we established the relationships among these kinds of functions. Finally, under the interval value invexity, the optimal condition of the interval valued optimization problem is established by using the scalarization method.

Key words: generalized convexity, interval value optimization problem, interval valued function, optimality condition
