Fuzzy subgroups of finite groups have been treated recently using
the concept of pinned-flags. In this paper, we consider the
operations of intersection, sum, product, and quotient of fuzzy
subgroups of finite abelian groups in general, in terms of
pinned-flags. We develop algorithms to construct pinned-flags of
fuzzy subgroups corresponding to these operations and prove their
validity. We illustrate some applications of such algorithms.
