The strict complementary slackness condition in linear fractional programming
Mahmood Mehdiloozad, Kaoru Tone, Mohammad Bagher Ahmadi
The strict complementary slackness condition (SCSC) is an important concept in the duality theory of linear programming (LP). The current study aims at extending this concept to th…
Measurement of returns to scale with weight restrictions: How to deal with the occurrence of multiple supporting hyperplanes?
Mahmood Mehdiloozad, Kaoru Tone, Biresh K. Sahoo
While measuring returns to scale in data envelopment analysis (DEA), the occurrence of multiple supporting hyperplanes has been perceived as a crucial issue. To deal effectively wi…
On the identification of the global reference set in data envelopment analysis
Mahmood Mehdiloozad, S. Morteza Mirdehghan, Biresh K. Sahoo +1
It is well established that multiple reference sets may occur for a decision making unit (DMU) in the non-radial DEA (data envelopment analysis) setting. As our first contribution,…
Identification of reference set and measurement of returns to scale in DEA: A least distance based framework
Mahmood Mehdiloozad, Mohammad Bagher Ahmadi
In data envelopment model (DEA), while either the most or least distance based frameworks can be implemented for targeting, the latter is often more relevant than the former from a…
Finding a maximal element of a convex set through its characteristic cone: An application to finding a strictly complementary solution
Mahmood Mehdiloozad, Kaoru Tone, Rahim Askarpour +1
In order to express a polyhedron as the (Minkowski) sum of a polytope and a polyhedral cone, Motzkin (1936) made a transition from the polyhedron to a polyhedral cone. Based on his…
