In this paper, we investigate the various relationships among the linear programming solutions of data envelopment analysis (DEA) models under a constant returns to scale technology. We derive the ...

Let Ω ⊂ ℝp, p ϵ ℕ* be a nonempty subset and B (Ω) be the Branch lattice of all bounded real functions on a Ω, equipped with sup norm. Let 𝑋 ⊂ 𝐵 (Ω) be a linear sublattice of 𝐵 (Ω) and 𝐴: 𝑋 → 𝑋 ...
