Reasoning about soft constraints and conditional preferences: complexity results and approximation techniques
Many real life optimization problems contain both hard and soft constraints, as well as qualitative conditional preferences. However, there is no single formalism to specify all t...

Temporal Reasoning with Preferences and Uncertainty
Temporal Constraint Satisfaction Problems allow for reasoning with events happening over time. Their expressiveness has been extended independently in two directions: to account f...

A Qualitative Trajectory Calculus and the Composition of Its Relations
Continuously moving objects are prevalent in many domains. Although there have been attempts to combine both spatial and temporal relationships from a reasoning, a database, as wel...

Extension of Petri Nets for Representing and Reasoning with Tasks with Imprecise Durations
This paper presents an extension of Petri net framework with imprecise temporal properties. We use possibility theory to represent imprecise time by time-stamping tokens and assig...

Representing and Reasoning about Motion in a Two-Dimensional World
This paper presents a point based spatio-temporal rst order logic for representing the qualitative and quantitative spatial temporal knowledge needed to reason about motion in a t...
