Public Functions Documentation

function ProbabilityAnalysis

ProbabilityAnalysis(
    const FaultTreeAnalysis * fta,
    mef::MissionTime * mission_time
)

Probability analysis with the results of qualitative analysis.

Parameters:

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

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

function ~ProbabilityAnalysis

virtual ~ProbabilityAnalysis() =default

function Analyze

void Analyze()

Performs quantitative analysis on the supplied fault tree.

Precondition: Analysis is called only once.

Postcondition: The mission time expression has its original value.

function p_total

inline double p_total() const

Return: The total probability calculated by the analysis.

Precondition: The analysis is done.

function p_time

inline const std::vector< std::pair< double, double > > & p_time() const

Return: The probability values over the mission time in time steps. The empty container implies no calculation has been done.

Precondition: The analysis is done.

function sil

inline const Sil & sil() const

Return: The Safety Integrity Level calculation results.

Precondition: The analysis is done with a request for the SIL.

Protected Functions Documentation

function mission_time

inline mef::MissionTime & mission_time()

Return: The mission time expression of the model.
