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