Public Functions Documentation

function Compute

template <typename T >
inline double Compute(
    T && eval
)

Computes the value for GLM expression.

function Compute

double Compute(
    double gamma,
    double lambda,
    double mu,
    double time
)

function Glm

Glm(
    Expression * gamma,
    Expression * lambda,
    Expression * mu,
    Expression * t
)

Constructor for GLM or exponential expression with four arguments.

Parameters:

• gamma Probability of failure on demand.
• lambda Hourly rate of failure.
• mu Hourly repair rate.
• t Mission time in hours.

function Validate

virtual void Validate() const override

Validates the expression.

Exceptions:

• DomainError The argument value domains are invalid.
• ValidityError The arguments are invalid for setup.

Reimplements: scram::mef::Expression::Validate

This late validation is due to parameters that are defined late.

function interval

inline virtual Interval interval() override

Return: The domain interval for validation purposes only.

Reimplements: scram::mef::Expression::interval
