Hierarchical Planning

Aliases: Plan Refinement, Top-down Plan Elaboration

Keywords: criticality, plan elaboration rules, preconditions

Categories: Planning


Author(s): Jim Doran

The technique by which a hierarchical plan structure is produced by successive generation, from top to bottom, of its component levels. One variant of the technique developed by Sacerdoti makes use of criticalities assigned to operator preconditions. More generally, it was found by Tate, for example, that domain specific plan elaboration rules are required. Top-down plan elaboration is closely related to automatic top-down programming techniques (see Barstow).
