Abstract

Recently, some authors proposed the use of symmetric weights
for computing the elements of cross-efficiency matrix. In spite of
the fact that the proposed method decreases the number of zero
weights, a large number of zero weights may still exist among input
and output symmetric weights. To decrease the number of input and
output symmetric weights, this paper improves the proposed secondary
goal model. The improved method generates more acceptable results in
the ranking process of the decision making units (DMUs). Finally, a
numerical example is provided to illustrate the applicability of the
proposed method.
