On some semilattice structures for production technologies

Tracing back from Charnes et al. many approaches have been proposed to extend the DEA production model to non‐convex technologies. The FDH method were introduced by Deprins et al. and it only assumes a free disposal assumption of the technology. This paper, continues further an earlier work by Briec and Horvath . Among other things, a new class of semilattice production technologies is introduced. Duality results as well as computational issues are proposed.
