This paper focuses on a special type of course-of-action. Specifically, performing study on planning with the existence of qualitative preferences and functions on the actions and owns the inner inconsistence. The course-of-action that is taken into consideration is called‘task-level’course-of-action(COA), with abstracted action as basic element. The qualitative preferences in discussion include static preferences and temporal preference. The objective of planning is a COA plan with satisfaction. Firstly, a unified formulated description is established for constraints and preferences, based on which an algorithm for COA planning is developed. Furthermore, computational argumentation is utilized to exclude inconsistence in the set of preferences, to maximize the user’s satisfaction for COA planning. The planning framework based on qualitative deduction is an effective add-in for conventional planning scheme based on quantitative computation. The property of preference-decoupling makes itself adaptable to applications in different domain. A case study on scheduling responsive imaging satellites is proposed to demonstrate the effectiveness of the scheme.
