Some practical issues in modeling diagnostic systems with multiply sectioned Bayesian networks

摘要

Multiply Sectioned Bayesian Networks (MSBNs) provide a distributed framework for diagnosis of large systems based on probabilistic knowledge. To ensure exact inference, the partition of a large system into subsystems and the representation of subsystems must follow a set of technical constraints. How to satisfy these goals for a given system may not be obvious to a practitioner. In this paper, we address three practical modeling issues.
