Probability analyzer provides the main engine for probability analysis.

Public Functions Documentation

function CalculateTotalProbability

virtual double CalculateTotalProbability(
    const Pdag::IndexMap< double > & p_vars
)

Calculates the total probability with a different set of probability values than the one given upon construction.

Parameters:

• p_vars A map of probabilities of the graph variables. The indices of the variables must map exactly to the values.

Return: The total probability calculated with the given values.

Reimplements: scram::core::ProbabilityAnalyzerBase::CalculateTotalProbability

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.
