Abstract

Time-critical dynamic decision making is a quite challenging task in many real-world applications. It requires to play a trade-off between solution optimality and computational tractability. It is especially true for multiagent settings under uncertainty. In this paper, we model time-critical dynamic decision problem using the representation of interactive dynamic influence diagram~(I-DID). We formalize I-DID by providing time-index to nodes within the model. This results in a model that has the ability to represent space-temporal abstraction. In addition, we propose a new method for selecting the abstract model without arbitrarily compromising solution optimality. We evaluate the performance of our method in two benchmark settings and provide results in support.
交互式动态影响图中的时间关键决策
在许多实际应用程序中,时间关键型动态决策是一项相当具有挑战性的任务。它需要在解决方案的最优性和计算可跟踪性之间进行权衡。对于不确定的多智能体设置尤其如此。本文利用交互动态影响图(I-DID)的表示对时间临界动态决策问题进行建模。我们通过向模型内的节点提供时间索引来形式化I-DID。这就产生了一个能够表示时空抽象的模型。此外,我们还提出了一种新的选择抽象模型的方法,该方法不会任意损害解的最优性。我们在两个基准设置中评估了我们的方法的性能,并提供了支持结果。
