The purpose of this paper is to define, in a natural way, an order relation on the set of antichains of an ordered set.Thus, the set of finite antichains becomes a sup-lattice.If moreover, the given ordered set is a strictly ordered commutative monoid, the finite antichains constitute also an ordered monoid.
