Logic programs with ordered disjunction (LPODs) combine ideas underlying Qualitative Choice Logic, a logic recently introduced by Brewka, Benferhat and Le Berre, and answer set programming. Logic programming under answer set semantics is extended with a new connective called ordered disjunction. The new connective allows us to represent alternative, ranked options for problem solutions in the heads of rules: A x B intuitively means: if possible A, but if A is not possible then at least B. The semantics of logic programs with ordered disjunction is based on a preference relation on answer sets. LPODs are useful for applications in design and configuration and can serve as a basis for qualitative decision making.
