摘要:

有一个越来越多的需要自动化的支持人类监测活动的分布式团队的合作代理,人类和机器。我们描述了这个问题所带来的独立于域的挑战,并描述了域的属性如何影响挑战及其解决方案。我们将专注于动态的、数据丰富的领域,在这些领域中,人类最终对团队行为负责。因此,自动化辅助应该交互地支持人类做出有效和及时的决策。我们提出了一个域独立的分类的警报类型的计划为基础的监测系统可能会向用户发出,其中每种类型通常需要不同的监测技术。我们描述了一个监控框架,用于集成许多特定于域和特定于任务的监控技术,然后使用警报值的概念来避免操作员过载。我们使用这个框架来描述一个执行监控方法,我们已经用来实现执行助理(EA)在两个不同的动态,数据丰富,现实世界的域,以协助人类在监控团队行为。一个域(陆军小单位作战)有数百个移动的、地理上分布的代理,是人类、机器人和车辆的组合。另一个领域(无人驾驶地面和空中车辆团队)有少数合作机器人。这两个领域都涉及附近不可预测的对手。我们的方法为每个特定的任务、计划和情况以及用户偏好定制监控行为。当报告的事件威胁到计划执行或对团队成员造成人身威胁时,我们的EA会向人类控制器发出警报。及时生成警报,而不会使用户淹没在过多的警报中(根据领域专家的判断,不到10%的警报是不需要的)。

英文摘要:

There is an increasing need for automated support for humans monitoring the activity of distributed teams of cooperating agents, both human and machine. We characterize the domain-independent challenges posed by this problem, and describe how properties of domains influence the challenges and their solutions. We will concentrate on dynamic, data-rich domains where humans are ultimately responsible for team behavior. Thus, the automated aid should interactively support effective and timely decision making by the human. We present a domain-independent categorization of the types of alerts a plan-based monitoring system might issue to a user, where each type generally requires different monitoring techniques. We describe a monitoring framework for integrating many domain-specific and task-specific monitoring techniques and then using the concept of value of an alert to avoid operator overload. We use this framework to describe an execution monitoring approach we have used to implement Execution Assistants (EAs) in two different dynamic, data-rich, real-world domains to assist a human in monitoring team behavior. One domain (Army small unit operations) has hundreds of mobile, geographically distributed agents, a combination of humans, robots, and vehicles. The other domain (teams of unmanned ground and air vehicles) has a handful of cooperating robots. Both domains involve unpredictable adversaries in the vicinity. Our approach customizes monitoring behavior for each specific task, plan, and situation, as well as for user preferences. Our EAs alert the human controller when reported events threaten plan execution or physically threaten team members. Alerts were generated in a timely manner without inundating the user with too many alerts (less than 10 percent of alerts are unwanted, as judged by domain experts).
