Abstract. Let
(S,=, � ,·,s) be an ordered semigroup under an antiorder
s. If S is a subdirect product of the ordered semigroup
{Si: i � I }, then there exists a family {si : i � I} of quasi-antiorders on S which separates the elements of
S. Conversely, if {si : i � I } is a family of
quasi-antiorders on S which separates the elements if S, then
S is a subdirect product of the ordered semigroups
{S / (si �(si)-1): i � I }.
