Abstract (EN)
The purpose of this paper is to present a structure, called pseudo-order, which could be taken as a model of preference for a decision-maker who hesitates, for cairs of actions, between indefference and preference. We will study its properties, particularly concerning its functional representation: the results obtained generalize the properties of such well-known structures as complete preorders and semi-orders.
