摘要:

我们描述了一个概率框架综合控制策略一般多机器人系统,给定的环境和传感器模型和成本函数。分散式部分可观测马尔可夫决策过程(Dec-POMDPs)是决策过程的一般模型,其中一组代理必须在存在不确定性的情况下合作优化某些目标(由共享奖励或成本函数指定),但其中通信限制意味着代理不能共享其状态,因此执行必须以分散的方式进行。虽然Dec-POMDP通常难以解决现实世界的问题,但最近关于Dec-POMDP中使用宏动作的研究显着增加了可以作为Dec-POMDP实际解决的问题的大小。我们描述了这个一般模型,并展示了如何,与大多数现有的方法,专门针对一个特定的问题类,它可以合成控制策略,使用任何机会协调存在的问题,同时平衡的不确定性的结果,传感器信息,和其他代理人的信息。我们使用三个变化的仓库任务,表明这种类型的一个单一的计划可以产生合作的行为,使用任务分配,直接沟通,和信令,适当的。

英文摘要:

We describe a probabilistic framework for synthesizing control policies for general multi-robot systems, given environment and sensor models and a cost function. Decentralized, partially observable Markov decision processes (Dec-POMDPs) are a general model of decision processes where a team of agents must cooperate to optimize some objective (specified by a shared reward or cost function) in the presence of uncertainty, but where communication limitations mean that the agents cannot share their state, so execution must proceed in a decentralized fashion. While Dec-POMDPs are typically intractable to solve for real-world problems, recent research on the use of macro-actions in Dec-POMDPs has significantly increased the size of problem that can be practically solved as a Dec-POMDP. We describe this general model, and show how, in contrast to most existing methods that are specialized to a particular problem class, it can synthesize control policies that use whatever opportunities for coordination are present in the problem, while balancing off uncertainty in outcomes, sensor information, and information about other agents. We use three variations on a warehouse task to show that a single planner of this type can generate cooperative behavior using task allocation, direct communication, and signaling, as appropriate.
