区间马尔可夫决策过程的合成推理

Compositional Reasoning for Interval Markov Decision Processes

Vahid Hashemi, Holger Hermanns, Andrea Turrini

摘要:

Puggelli等人最近研究了具有凸不确定性的Markov决策过程的模型检验概率CTL性质,这类模型检验算法通常存在状态空间爆炸问题.在本文中,我们解决概率互模拟,以减少这样的MDP的大小,同时保持概率CTL属性,它满足。特别是,我们讨论的关键成分,建立在运行时组成间隔MDP组件的并行组合操作。更确切地说,我们研究如何并行组合操作的区间MDP可以定义,以便达到一个同余闭包。其结果是,我们表明,概率互模拟区间MDPs是一致的两个方面的并行性,即同步产品和交织。

英文摘要:

Model checking probabilistic CTL properties of Markov decision processes with convex uncertainties has been recently investigated by Puggelli et al. Such model checking algorithms typically suffer from the state space explosion. In this paper, we address probabilistic bisimulation to reduce the size of such an MDP while preserving the probabilistic CTL properties it satisfies. In particular, we discuss the key ingredients to build up the operations of parallel composition for composing interval MDP components at run-time. More precisely, we investigate how the parallel composition operator for interval MDPs can be defined so as to arrive at a congruence closure. As a result, we show that probabilistic bisimulation for interval MDPs is congruence with respect to two facets of parallelism, namely synchronous product and interleaving.
