  In this paper, we consider interval-valued vector optimization problems
$(IVOP)$ and derive their relationships to interval vector variational
inequalities $(IVVI)$ of Minty and Stampacchia type in terms of convexificators
and LU-efficient solution of $(IVOP)$ using LU-convexity assumption.
Furthermore, we consider weak versions of $(IVVI)$ of Minty and Stampacchia
type and find the relationships between weak versions of $(IVVI)$ of Minty and
Stampacchia type and weakly LU-efficient solution of $(IVOP)$. The results
presented in this paper extend and generalized some existing results in the
literature.
