Goal Structure, Holding Periods and 'Clouds'

Abstract

This paper briefly describes the representation of plans used in the Edinburgh O-Plan knowledge based planning system. The representation allows for the modelling of relative and metric time and metric resource constraints. The O-Plan system structure is mentioned.

The main body of the paper describes the representation of effects and conditions in a plan. It lists the Support Operations often required in an AI planner. The used of a "cloud" as an abstractions of a potentially large set of effects (and effects caused by events external to the plan) and how this structure is used within the planner to replace earlier "Goal Structure" maintenance packages in planners is described.
