Abstract

In this paper, we present an approach of temporal probabilistic task planning. Each task has a set of temporal constraints, a set of probabilities and a set of constant costs. Tasks are connected in an acyclic AND/OR Graph. Our planner constructs a plan formed by a subset of tasks chosen to be executed in order to achieve some goals, satisfy all constraints and has a high probability of execution during a minimal total time and with a reduced cost. This approach is one of the first techniques combining probability and time in planning using an AND/OR graph.
