Presenting Free Disposal Hull Graphically

This paper introduces a methodology for presenting Decision Making Units (DMU) with multi-inputs and multi-outputs in a plane for Free Disposal Hull (FDH) efficiency evaluation. In this method, we can plot each DMU in a separate figure and find its references respect to variable, constant, non-increasing and non-decreasing returns to scale by a simple trade-off between DMUs avoiding the resolution of the corresponding integer linear or, alternatively, linear programs.
