Modeling the Evolution of Objects in Temporal Information Systems
This paper presents a semantic foundation of temporal conceptual models used to design temporal information systems. We consider a modeling language able to express both timestampi...

Planning with Problems Requiring Temporal Coordination
We present the first planner capable of reasoning with both the full semantics of PDDL2.1 (level 3) temporal planning and with numeric resources. Our planner, CRIKEY3, employs heu...

Representation and Reasoning with Disjunctive Temporal Constraints
We show the expressiveness provided by a Labelled point-based metric model for specifying and reasoning about complex disjunctive temporal constraints. The model allows us to mana...
