We introduce a new type of the system of generalized strong vector quasiequilibrium problems with set-valued mappings in real locally convex Hausdorff topological vector spaces. We establish an existence theorem by using Kakutani-Fan-Glicksberg fixed-point theorem and discuss the closedness of strong solution set for the system of generalized strong vector quasiequilibrium problem. The results presented in the paper improve and extend the main results of Long et al. 2008 . 1. Introduction The equilibrium problem is a generalization of classical variational inequalities. This problem contains many important problems as special cases for instance optimization Nash equilibrium complementarity and fixed-point problems see 1-3 and the references therein . Recently there has been an increasing interest in the study of vector equilibrium problems. Many results on existence of solutions for vector variational inequalities and vector equilibrium problems have been established see . 4-16 . Let X and Z be real locally convex Hausdorff space K c X a nonempty subset and C c Z be a closed convex pointed cone. Let F K X K 2Z be a given set-valued mapping. Ansari et al. 17 introduced the .
