Public Functions Documentation

function ProbabilityAnalyzerBase

template <class Algorithm >
inline ProbabilityAnalyzerBase(
    const FaultTreeAnalyzer< Algorithm > * fta,
    mef::MissionTime * mission_time
)

Constructs probability analyzer from a fault tree analyzer.

Parameters:

• fta Fault tree analysis with results.
• mission_time The mission time expression of the model.

Template Parameters:

• Algorithm Qualitative analysis algorithm.

Precondition: The underlying fault tree must not have changed in any way since the fault tree analysis finished.

function graph

inline Pdag * graph() const

Return: The original PDAG from the fault tree analyzer.

function products

inline const Zbdd & products() const

Return: The resulting products of the fault tree analyzer.

function p_vars

inline const Pdag::IndexMap< double > & p_vars() const

Return: A mapping for probability values with indices.

function fault_tree_analysis

inline const FaultTreeAnalysis * fault_tree_analysis() const

Return: Pointer to the originating fault tree analysis.

function ApplyInitiatingEventFrequency

inline double ApplyInitiatingEventFrequency(
    double probability
) const

function initiating_event_frequency

inline double initiating_event_frequency() const
