org.jreliability.function.common.ExponentialReliabilityFunction

All Implemented Interfaces:

Function, ReliabilityFunction

Direct Known Subclasses:

ExponentialFailureFunction

public class ExponentialReliabilityFunction
extends SequentialFunction
implements ReliabilityFunction

The ExponentialReliabilityFunction represents the exponential ReliabilityFunction
R(x) = 1 - F(x) = e^-(alpha * x)
with alpha > 0.

Typical for this ReliabilityFunction is the constant failure-rate lambda that equals the parameter alpha.
