Abstract
Tracing back from Charnes, Cooper and Rhodes (1978) many approaches have been proposed to extend the DEA production model to non-convex technologies. The FDH method were introduced by Deprins, Simar and Tulkens (1984) and it only assumes a free disposal assumption of the technology. This paper gives an overview of recent contributions involving a semilattice structure of production technologies. Some additional developments about Tropical technologies are also presented.
