Formulation | Brief Description |
1. Simple Efficiency Score | Basic formulation A self-evaluation mode Weak discriminating power Unrealistic weights |
2. Aggressive Cross Efficiency Score | All DMUs are used in the calculation of the efficiency The set of weights reduces the cross-efficiency score for the other DMUs Provides a unique ordering of the DMUs A peer-evaluation mode Eliminates unrealistic weights |
3. Aggressive off Diagonal Cross Efficiency Score | Diagonal DMUs are not used in the calculation of the efficiency The set of weights reduces the cross-efficiency score for the other DMUs Provides a unique ordering of the DMUs A peer-evaluation mode Eliminates unrealistic weights |
4. Benevolent Cross Efficiency Score | All DMUs are used in the calculation of the efficiency The set of weights leads to higher a cross-efficiency scores for the other DMUs Provides a unique ordering of the DMUs A peer-evaluation mode Eliminates unrealistic weights |
5. Benevolent off Diagonal Cross Efficiency Score | Diagonal DMUs are not used in the calculation of the efficiency The set of weights leads to higher a cross-efficiency scores for the other DMUs Provides a unique ordering of the DMUs A peer-evaluation mode Eliminates unrealistic weights |
6. Super Efficiency | Discrimination is based on using the super efficiency formulation |
7. Aggressive Maverick Score | Discrimination is based on calculating the Maverick score using aggressive efficiencies |
8. Benevolent Maverick Score | Discrimination is based on calculating the Maverick score using benevolent efficiencies |
