BOPfailure1: BOPfailure Bayesian Networks

Description

Providing a comprehensive approach to oil well blowout risk assessment.

Arguments

Value

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

Format

A discrete Bayesian network for risk assessment of oil well blowout (Fig. 5 of the referenced paper). Probabilities were given within the referenced paper. The vertices are:

X4

Line failure (F, S);

X5

Choke manifold failure (F, S);

X6

Annular preventer (F, S);

X7
