      <field key="753" subkey="">Abstract: Some models are presented in this paper which extend the concept of measuring superefficiency to the useful case of</field>
      <field key="var" subkey="i">able returns-to-scales (VRS), thus enabling the ranking of efficient as well as inefficient units. Two models, namely the</field>
      <field key="Uni" subkey="v">ersal Radial Model and the Universal Additive Model, are presented that also have strong invariance properties (units and</field>
      <field key="tra" subkey="n">slation invariance). For both of these models a method for normalising the efficiency scores on a (0-1+) scale is presented.</field>
      <field key="The" subkey="s">e models have been implemented in a software package and applied to the ranking of units in an industrial context.;</field>
