Abstract
This paper shows that the Sueyoshi and Chang [Ops. Res. Lett. 8, 205-2 13 (1989)] remedy for Charnes et al. [Socio-Econ. Planning Sci. 16, 22 3-224 (1982); Ops Res. Lett. 2, 101-103 (1983)] multiplicative (or log ) efficiency measure is not unit invariant, and Banker and Maindiratta 's [Mgmt Sci. 32, 126-135 (1986)] approach should use positive-multipl ier loglinear production frontiers to evaluate decision-making-units ( DMUs). The paper also proposes a distance-oriented efficiency measure: the distance efficiency measure, which for the case of constant outpu t and the case of linearly homogeneous production technology is unit i nvariant.
