Reconnecting Subnets in a Decision Architecture

The Decision Architecture (DA) being developed for MDA within project Hercules consists of a large Bayes' net designed to combine information from multiple sources and systems to help make decisions about the number, kinematic state, and types of targetspresent during all phases of a ballistic missile attack. The DA will integrate information from a number of disparate subsystems in several locations. During this process it may be useful or necessary for one or more of these subsystems to operate inisolation without sending or receiving information from the rest of the DA. The proposed work will use the results of our phase I work to develop a prototype software system that can (1) connect or reconnect a subnet to rest of the decision architecturein such a manner that information from the subnet is correctly and optimally integrated into the Bayes' net representing the rest of the DA; (2) dynamically reconfigure the net to account for new targets, and (3) incorporate Gaussian andnon-Gaussian,continuous measurement information at leaf nodes. The goal is to develop this prototype software so that it can be integrated into the DA.
