ABGT (jreliability v2.0 API)

java.lang.Object
- org.jreliability.importancemeasures.ABGT<T>

Type Parameters:

T - The type of the variables of the BDD of the system

All Implemented Interfaces:

```
    Returns a ABGT calculator for a specific system with its BDD and ReliabilityFunction Transformer.
    
    Parameters:
    
    bdd - The BDD representing the system structure function
    
    transformer - The Transformer used to get the ReliabilityFunction of variables present in the BDD
- Method Detail
  - calculate
```
public java.util.Map<T,java.lang.Double> calculate(double time)
```
    Calculates the ABGT importances for all components at the specified time. Uses equation 15 and 23 of [ABGT17] to calculate the importance from the failure and repair CriticalityBDDs of the components.
    
    Specified by:
    
    calculate in interface TimeDependentImportanceMeasure<T>
    
    Parameters:
    
    time - Time t at which the ABGT importance of all components is calculated. Must be greater than 0, otherwise an IllegalArgumentException is thrown.
    
    Returns:
    
    results Map of components and their respective ABGT importance at time t.
