论文摘要
我们研究小组决策，而不断变化的偏好是马尔可夫决策过程。随着时间的流逝，在为一群人做出选择时，自动化决策系统的普遍性日益增加。我们的主要贡献是展示社会选择理论中的经典表示理论如何适应这种动态环境中的最佳政策。我们提供了MDP奖励功能的公理表征，该功能与社会选择理论的实用社会福利功能一致。当社会选择理论公理的实施可能无法导致长期最佳结果时，我们还提供了有关案例的讨论。
We study group decision making with changing preferences as a Markov Decision Process. We are motivated by the increasing prevalence of automated decision-making systems when making choices for groups of people over time. Our main contribution is to show how classic representation theorems from social choice theory can be adapted to characterize optimal policies in this dynamic setting. We provide an axiomatic characterization of MDP reward functions that agree with the Utilitarianism social welfare functionals of social choice theory. We also provide discussion of cases when the implementation of social choice-theoretic axioms may fail to lead to long-run optimal outcomes.
