基于可能性理论的定性决策公理化方法比较

A Comparison of Axiomatic Approaches to Qualitative Decision Making Using Possibility Theory

University of Kansas(堪萨斯大学)

Phan H. Giang, Prakash P. Shenoy

摘要:

在本文中,我们分析了两个最近的公理化方法提出的Dubois等人和Giang和Shenoy定性决策的不确定性描述的可能性理论。这两个公理化的灵感来自冯诺依曼和摩根斯特恩的公理系统的情况下概率论。我们表明,我们的方法自然地统一了两个公理系统,分别对应于Dubois等人提出的悲观和乐观的决策标准。简化统一是通过(i)替换公理,应该反映两种信息态度(不确定性厌恶和不确定性吸引力)的公理,规定了一套标准的彩票和(ii)使用二进制效用量表,其中每个效用水平由一对数字表示。

英文摘要:

In this paper we analyze two recent axiomatic approaches proposed by Dubois et al and by Giang and Shenoy to qualitative decision making where uncertainty is described by possibility theory. Both axiomtizations are inspired by von Neumann and Morgenstern's system of axioms for the case of probability theory. We show that our approach naturally unifies two axiomatic systems that correspond respectively to pessimistic and optimistic decision criteria proposed by Dubois et al. The simplifying unification is achieved by (i) replacing axioms that are supposed to reflect two informational attitudes (uncertainty aversion and uncertainty attraction) by an axiom that imposes order on set of standard lotteries and (ii) using a binary utility scale in which each utility level is represented by a pair of numbers.
