A lexicographic radial projection onto the efficient frontier in Data Envelopment Analysis.
European Journal of Operational Research(2018)
摘要
•A lexicographic approach radially projects units onto the efficient frontier.•Components of the radial projection vector are dropped step by step.•The target on the efficient frontier is found in the spirit of radial projection.•The (in)efficiency score is individual for all controllable variables.•A numerical illustration and an empirical example demonstrate the approach.
