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 for uncontrollable events, and, more recently, to account for soft temporal preferences. The motivation for both extensions is from real-life temporal problems; and indeed such problems may well necessitate both preferences and uncertainty. This paper proposes the study of temporal problems with both preferences and uncertainty, and puts forward some methods for their resolution. 1 Motivation and Background Research on temporal reasoning, once exposed to the dif£culties of real-life problems, can be found lacking both expressiveness and ¤exibility. Planning and scheduling for satellite observations, for instance, involves not only quantitative temporal constraints between events and qualitative temporal ordering of events, but also soft temporal preferences and contingent events over which the agent has no c...
