[EN] This paper presents a planning system that uses defeasible argumentation to reason about
context information during the construction of a plan. The system is designed to operate
in cooperative multi-agent environments where agents are endowed with planning and
argumentation capabilities. Planning allows agents to contribute with actions to the construction
of the plan, and argumentation is the mechanism that agents use to defend or
attack the planning choices according to their beliefs. We present the formalization of the
model and we provide a novel specification of the qualification problem. The multi-agent
planning system, which is designed to be domain-independent, is evaluated with two planning
tasks from the problem suites of the International Planning Competition. We compare
our system with a non-argumentative planning framework and with a different approach
of planning and argumentation. The results will show that our system obtains less costly
and more robust solution plans.This work has been partly supported by the Spanish MINECO under project TIN2014-55637-C2-2-R and the Valencian project PROMETEO II/2013/019.Pajares Ferrando, S.; Onaindia De La Rivaherrera, E.
