Goals rarely occur in isolation. Efficient planning for conjunctive goals is therefore of central interest. We identify a particular class of conjunctive goal interactions, which cannot be directly inferred from the domain knowledge, as they are not explicitly represented in the preconditions and effects of the domain operators. We call such goal interactions, quality goal interactions, for they relate to issues on plan quality rather than to the common plan achievement issues. We illustrate the discussion with examples and briefly present the method we are developing for acquiring control knowledge to direct the planner to consider the quality-goal interactions.
