In the present paper, we prove that certain parametrized multiple series
satisfy the same relation as Ohno's relation for multiple zeta values. This
result gives us a generalization of Ohno's relation for multiple zeta values.
By virtue of this generalization, we obtain a certain equivalence between the
above relation among the parametrized multiple series and a subfamily of the
relation. As applications of the above results, we obtain some results on
multiple zeta values.
