It is assumed in the standard DEA model that the aggregate output (input) is a pure linear function of each output (input). This means, for example, that if DMU j1 generates twice as much of an output as does another DMU j2, then the former is credited with having created twice as much value. In many situations, however, linear pricing ðlryrjÞ may not adequately reflect differences in value created from one DMU to another. In this paper, a generalization of the DEA methodology is presented that… CONTINUE READING
