lem. In addition to that, we establish relationship be- tween vector variational inequality problems and mul- tiobjective interval valued Optimization problems un- der the assumption ofLUconvex smooth and nons- mooth objective functions.Motivated by the work of Wu [3], Andreaniet al.
[16], Haeser and Schuverdt [10], Mastroeni [11] andGiorgiet al.[9], we introduce Approximate-Karush-
Kuhn-Tucker optimality conditions for interval val- ued objective function and discuss the sufficiency ofAKKTconditions for the interval valued problems
and generalize its definition to the structure of vector variational inequality problems.The organization of this paper is as follows: In
Section 2, we collected some basic definitions and re- sults. In Section 3, we develop sequential optimality conditions asAKKTconditions for interval valued vector variational inequality problem and proved suf- ficiency withLUconvex and affine conditions.2 Preliminaries
2.1 Interval Analysis
We collect some basic concepts and essential defini- tions related to interval valued functions.We denote byIthe class of all closed intervals in
R :LetU= [uL;uU];whereuLanduUdenotes the lower and upper bounds ofU;respectively. LetU= [uL;uU]andV= [vL;vU]be inI;then, we
have (i)U+V=fu+v:u2U; v2Vg= [uL+ vL;uU+vU];
(ii)U=fu:u2Ug= [uU;uL]; (iii)UV=U+ (V) = [uLvU;uUvL]; (iv)tU=ftu:u2Ug=[tuL;tuU]ift0 tuU;tuL]fort <0
