We go deeper into the study of the Dominance Plausible Rule (DPR) model of preferences over acts due to Dubois et al. This model corresponds, in the qualitative framework, to Savage’s model. The DPR model relies on two purely ordinal primitives: (1) a preference over consequences and (2) a plausibility relation over sets of states of the world. We characterize several versions of the model defined by different classes of plausibility relations. Our representation results also show that the model has interesting rationality properties. As a consequence of our characterizations, we obtain subjective plausibility relations of several kinds.

通过支配合理规则进行决策：新特征

我们更深入地研究了 Dubois 等人对行为的偏好的支配合理规则 (DPR) 模型。在定性框架中，该模型对应于 Savage 的模型。DPR 模型依赖于两个纯粹的有序原语：（1）对结果的偏好和（2）对世界状态集的合理性关系。我们描述了由不同类别的似然关系定义的模型的几个版本。我们的表示结果还表明该模型具有有趣的合理性。作为我们表征的结果，我们获得了几种主观合理性关系。
