Formulation

Brief Description

1. Simple Efficiency Score

Ÿ Basic formulation

Ÿ A self-evaluation mode

Ÿ Weak discriminating power

Ÿ Unrealistic weights

2. Aggressive Cross Efficiency Score

Ÿ All DMUs are used in the calculation of the efficiency

Ÿ The set of weights reduces the cross-efficiency score for the other DMUs

Ÿ Provides a unique ordering of the DMUs

Ÿ A peer-evaluation mode

Ÿ Eliminates unrealistic weights

3. Aggressive off Diagonal Cross Efficiency Score

Ÿ Diagonal DMUs are not used in the calculation of the efficiency

Ÿ The set of weights reduces the cross-efficiency score for the other DMUs

Ÿ Provides a unique ordering of the DMUs

Ÿ A peer-evaluation mode

Ÿ Eliminates unrealistic weights

4. Benevolent Cross Efficiency Score

Ÿ All DMUs are used in the calculation of the efficiency

Ÿ The set of weights leads to higher a cross-efficiency scores for the other DMUs

Ÿ Provides a unique ordering of the DMUs

Ÿ A peer-evaluation mode

Ÿ Eliminates unrealistic weights

5. Benevolent off Diagonal Cross Efficiency Score

Ÿ Diagonal DMUs are not used in the calculation of the efficiency

Ÿ The set of weights leads to higher a cross-efficiency scores for the other DMUs

Ÿ Provides a unique ordering of the DMUs

Ÿ A peer-evaluation mode

Ÿ Eliminates unrealistic weights

6. Super Efficiency

Ÿ Discrimination is based on using the super efficiency formulation

7. Aggressive Maverick Score

Ÿ Discrimination is based on calculating the Maverick score using aggressive efficiencies

8. Benevolent Maverick Score

Ÿ Discrimination is based on calculating the Maverick score using benevolent efficiencies
