摘要:

在本文中,我们开发了一个定性理论的影响图,可用于建模和解决顺序决策任务时,只有定性(或不精确)的信息。我们的方法是基于概率和效用的数量级近似的顺序,并允许通过设置效用值指定部分排序的偏好。我们还提出了一个专用的变量消除算法,可以应用于解决数量级的影响图。

英文摘要:

In this paper, we develop a qualitative theory of influence diagrams that can be used to model and solve sequential decision making tasks when only qualitative (or imprecise) information is available. Our approach is based on an order-of-magnitude approximation of both probabilities and utilities and allows for specifying partially ordered preferences via sets of utility values. We also propose a dedicated variable elimination algorithm that can be applied for solving order-of-magnitude influence diagrams.
