An Architecture for Argumentation-based Epistemic Planning: A First Approach with Contextual Preferences

Argumentation-based planning systems present an interesting proposal for complex and dynamic domains where defeasible argumentation is used in the reasoning processes during the construction of plans by considering the available knowledge. In many real-world application scenarios, knowledge is provided with explicit priorities. Despite its importance, existing planning systems do not provide additional reasoning capacities of dynamically changing the preferences expressed by these priorities when a plan is being constructed. In this article, we present an argumentation and planning architecture, and propose a set of software engineering guidelines to analyze and design planning systems leveraging this capacity.
