Efficiency Analysis: How to Use Data Envelopment Analysis to Compare Efficiencies of Garages

Constraints

The following constraints are used in this example:

  • bounds on variables

  • for $i \in \text {INPUTS}$,

    \[ \sum _{j \in \text {GARAGES}} \Argument{input[i,j]} \cdot \Variable{Weight[j]} \le \Argument{input[i,k]} \]

  • for $i \in \text {OUTPUTS}$,

    \[ \sum _{j \in \text {GARAGES}} \Argument{output[i,j]} \cdot \Variable{Weight[j]} \ge \Argument{output[i,k]} \cdot \Variable{Inefficiency} \]
