Abstract: Min-based possibilistic influence diagrams allow a compact modelling of decision problems under uncertainty. Uncertainty and preferential relations are expressed on the same structure by using ordinal data. Like probabilistic influence diagrams, min-based possibilistic influence diagrams contain three types of nodes: chance, decision and utility nodes. Uncertainty is described by means of possibility distributions on chance nodes and preferences are expressed as satisfaction degrees on utility nodes. In many applications, it may be natural to represent expert knowledge and preferences separately and treat all nodes similarly. This paper shows how an influence diagram can be equivalently represented by two possibilistic networks: the first one represents knowledge of an agent and the second one represents agent’s preferences. Thus, the decision evaluation process is based on more compact possibilistic network.
