The problem "given A in V (n), B in V (m) and B' in V (m) find all A' in V (n) such that A' degrees (A x B) = B'", where degrees denotes max-min composition, x denotes Cartesian product and V (n) denotes the set of all fuzzy vectors with n members, is investigated. The condition for the existence of a solution is shown and an analytical solution is given.
