This paper addresses the problem of planning with preferences using Multiple Criteria Decision Analysis (MCDA) mechanisms. We start by explaining how PDDL3 preferences can be modelled by criteria from the Multi-Attribute Utility Theory (MAUT) along with a Choquet integral. Interestingly, preferences formalized using MAUT have almost the same expressiveness as the ones formalized in PDDL3 while being much easier to model. Next, we present a new heuristic for planning with preferences which is based on the Choquet integral. Finally, we introduce CHOPLAN a proof-of-concept planner solving main-encoded planning problems using the aforementioned heuristic. CHOPLAN'S performances are evaluated with respect to state of the art planners using problems from the fifth International Planning Competition.
