%0 Journal Article %T A Multi-Agent Extension of a Hierarchical Task Network Planning Formalism %A Rafael Cau¨º CARDOSO %A Rafael Heitor BORDINI %J - %D 2017 %R http://dx.doi.org/10.14201/ADCAIJ201762517 %X Describing planning domains using a common formalism promotes greater reuse of research, allowing a fairer comparison between different planners and approaches. Common planning formalisms for single-agent planning are already well established (e.g., PDDL, STRIPS, and HTN), but currently there is a shortage of multi-agent planning formalisms with clear semantics. In this paper, we propose a multi-agent extension of the Hierarchical Task Network (HTN) planning formalism for multi-agent planning problems. Our formalism, the Multi-Agent Hierarchical Task Network (MA-HTN), can be used to specify and represent multi-agent planning domains and problems. We provide a grammar with semantics for the domain and problem representation, and describe two case studies with the translation from multi-agent systems developed in JaCaMo to our MA-HTN formalism %K multi-agent planning %K hierarchical task network %K planning formalism %K SHOP2 %K JaCaMo %U http://campus.usal.es/~revistas_trabajo/index.php/2255-2863/article/view/ADCAIJ201762517
