Résumé : Given two finite posets P and Q, P is a chain minor of Q if there exists a partial function f from the elements of Q to the elements of P such that for every chain in P there is a chain CQ in Q with the property that f restricted to CQ is an isomorphism of chains. We give an algorithm to decide whether a poset P is a chain minor of a poset Q that runs in time O(
