Individual DMU Problem

BDisposal.dmuEfficiency — Function
 dmuEfficiency(I₀,O₀,I,O)

Compute the efficiency score for a DMU using vanilla Data Envelope Analysis.

Parameters:

  • I₀: This DMU inputs (nI)
  • O₀: This DMU outputs (n0)
  • I: All DMUs inputs (nDMU x nI)
  • O: All DMUs outputs (nDMU x n0)

Returns:

  • A named tuple with:
    • computed: a boolean to indicase wheter the underlying optimisation succeeded
    • eff: a boolean to indicate if the DMU is efficient or not
    • obj: a scalar representing the efficiency score of the DMU
    • wI: a vector of the optimal input weights
    • wO: a vector of the optimal output weights
    • refSet: a dictionary having as key the numeral of the reference DMUs and
    values the relative constraint duals
