Guaranteeing Real-Time Response with Limited Resources

Abstract: Certain patient-monitoring domains require real-time response to unanticipated events in order to provide high-quality care and avoid catastrophic outcomes. In this paper, we present an approach for guarenteeing a response to such events even in situations where we have limited problem-solving resources. We show that an action-based hierarchy can accomplish this goal. We also analyze the performance of this hierarchy under varying resouce availability and discuss decision-theoretic approaches to enable us to best structure such a hierarchy. We also describe an implementation of these ideas, called ReAct, in the BB1 architecture. All the ideas are illustrated with examples from the surgical intensive care unit (SICU) patient monitoring domain.
