bnRep (version 0.0.3)

polymorphic: polymorphic Bayesian Network

Description

Reliability analysis of high-voltage drive motor systems in terms of the polymorphic Bayesian network.

Value

An object of class bn.fit. Refer to the documentation of bnlearn for details.

Format

A discrete Bayesian network to depict the high-voltage drive motor system’s miscellaneous fault states. Probabilities were given within the referenced paper. The vertices are:
