Propice-Plan: Toward a Unified Framework for Planning and Execution

In this paper, we investigate the links between planning and plans execution. We propose a new approach (Propice-Plan) which integrates both activities. It implements supervision and execution capabilities, combined with diierent planning techniques: { plan synthesis to complement existing operational plans; and { anticipation planning to advise the execution for the best option to take when facing choices (by anticipating plans execution), and to forecast problems that may arise due to unforeseen situations. This approach relies on a common language to represent plans, actions, operational procedures and constraints. In particular, the description we propose makes transitions between planning activities and execution seamless. This work is used in two complex real-world problems: planning and control for autonomous mobile robots, and for the transition phases of a blast furnace.
