Detailed Description

template <class Algorithm >
class scram::core::FaultTreeAnalyzer;

Fault tree analysis facility with specific algorithms.

Template Parameters:

• Algorithm Fault tree analysis algorithm.

This class is meant to be specialized by fault tree analysis algorithms.

Public Functions Documentation

function algorithm

inline const Algorithm * algorithm() const

Return: The analysis algorithm for use by other analyses.

function FaultTreeAnalysis

FaultTreeAnalysis(
    const mef::Gate & root,
    const Settings & settings,
    const mef::Model * model =nullptr
)

Traverses a valid fault tree from the root gate to collect databases of events, gates, and other members of the fault tree.

Parameters:

• root The top event of the fault tree to analyze.
• settings Analysis settings for all calculations.
• model The Model containing substitutions if any.

Note: It is assumed that analysis is done only once.

Warning: If the fault tree structure is changed, this analysis does not incorporate the changed structure. Moreover, the analysis results may get corrupted.

The passed fault tree must be pre-validated without cycles, and its events must be fully initialized.

function graph

inline Pdag * graph() const

Return: Pointer to the PDAG representing the fault tree.
