A NON MATEMATICAL PROGRAMMING APPROACH TO FREE DISPOSAL HULL MODELS

The free Disposal Hull (FDH) introdaced by Deprins et al. is based on presenting a Production Pssibility Set (PPS) whithout assumption of cinvexity by a MILP model, Deprins et al. proposed an algorithm to solve FDH model without solving a MILP. Their model is a variable returns to scale FDH model. In this paper we introduce constant, non-decreasing and non-increasing FDA model in both LP and MILP forms and extend their algorithm to solve all of these models without solving any LP or MILP models.
