By applying hybrid inclusion and disclusion systems (HIDS), we establish several vectorial variantsof system of Ekeland's variational principle on topological vector spaces, some existence theorems of system of parametric vectorial quasi-equilibriumproblem, and an existence theorem of system of the Stampacchia-type vectorial equilibrium problem. As an application, a vectorial minimization theorem isalso given. Moreover, we discuss some equivalence relations between our vectorial variant of Ekeland's variational principle, common fixed pointtheorem, and maximal element theorem
