TL;DR: Polyhedral Cone-Ratio Data Envelopment Analysis Models generalizing the CCR Ratio Model are developed for situations with a finite number of DMUs and employing polyhedral cones of virtual multipliers as discussed by the authors.

TL;DR: In this paper, the essential properties of multiobjective programming in real normed linear spaces are studied and necessary and sufficient conditions for nondominated solutions under regularity and Frechet differentiability assumptions are developed.
