Abstract
A domain-specific software architecture (DSSA) is presented that supports development of a variety of intelligent patient monitoring (IPM) agents through component reuse and reconfiguration. Specifically, the IPM DSSA comprises: (a) a reference architecture that supports the shared functional requirements of IPM agents and provides a framework for configuring diverse application-specific sets of components; (b) principles for decomposing IPM expertise into highly reusable components, along with a growing library of such components; and (c) an interactive applications configuration tool that helps a user to select application-relevant components from the library and automatically configures selected components within the architecture. The efficacy of the IPM DSSA is demonstrated with results from the Guardian project, a series of experimental agents for monitoring intensivecare patients.
