Abstract: Traditional DEA models cannot deal with intermediate products since every activity should belong to either an input or an output but not to both; that is, the models neglect internal or linking activities. Network DEA models that can deal with intermediate products were introduced by Fare and Grosskopf [3], [4] and extended by some authors [5], [7] et al. Their models adopt the radial measure of efficiency as the basic DEA methodology. The radial models are adequate for some problems in which inputs or outputs undergo proportional changes but not suitable for the problem with inputs or outputs changing nonproportionally. So, Tone and Tsutui [8] have introduced slacks-based network DEA model which is non-radial model and is suitable for measuring efficiencies when inputs and outputs may not change proportionally; note that in the models of [8], they assume that all data are positive because they employ the slacks-based measure that demands positive data. In this paper, we introduce the Additive Network DEA model which is an extension of Additive model introduced by Pastor [6]. The model is a non-radial model and has a property known as“translation invariance”; from this property, we can deal with negative data in some of the inputs or outputs. This model can be applied to several problems not only with internal or linking activities but also with losses as well as profits treated as output. We will apply the model to financial analysis of machinery and appliance manufacturers.
