摘   要：
Eiichi Bannai and Etsuku Bannai classified association schemes with multiple $P$-polynomial structures and Hiroshi Suzuki classified those with multiple $Q$-polynomial structures. We are concerned with the existence of these schemes, in particular, schemes with $P$- or $Q$-polynomial structures of type III. We will mention a few related problems.
