Identification of all DEA efficient facets

The ability of identifying efficient frontier prior to the DEA calculation is of extreme importance to an effective and efficient DEA computation. We introduce a new computational framework which is based on enumerating the extreme points of a convex polytope specified by some linear constraints. The number of extreme points of the proposed model is about equal to the number of efficient facets of the production possibility set (PPS). Access to efficient frontier of PPS permits a complete analysis in a second phase for the corresponding model either oriented or orientation-free.
