Planning Constraint Set

Data artifactCognitionCognition & Memoryarc:PlanningConstraintSet

Declarative resource capacities, temporal (deadline, duration, synchronisation) constraints and global state invariants that every valid plan must respect throughout execution.

Responsibility. Defines resource, temporal and state-invariant limits on permissible plans.

Also known as: Resource constraints, Temporal constraints, State constraints / global invariants
