•
Scheduling and resource allocation, in which the action models include the
above types of constraints plus constraints on the resources to be used by
each action. A scheduling tool takes as input the actions to be carried out
together with resource constraints and optimization criteria. The tool returns
a temporal organization and resource allocation for the given actions in order
to meet all the constraints and optimize the criteria.
•
Plan synthesis, in which the action models enrich the precedent models with
the conditions needed for the applicability of an action and the effects of the
action on the state of the world. A plan synthesis tool takes as input the models
of all known actions, a description of the
