Abstract
We propose in this paper an extension to the Zero Sum Gains Data Envelopment Analysis model (ZSG-DEA). The proposed approach takes into account, simultaneously, non-radial projections and cone-ratio weights restrictions. We developed an iterative approximate algorithm to solve this model, as in the case study it is oriented only to the constant sum output. The theoretical approach is applied to the concession of discounts and surcharges problem, in terms of airport fees.
É proposta neste artigo uma extensão do modelo de Análise de Envoltória de Dados com Ganhos de Soma Zero (DEA-GSZ). Esta extensão considera simultaneamente projeções não radiais e restrições do tipo cone-ratio. Mostra-se necessário para a resolução do modelo proposto, o uso de um algoritmo iterativo aproximado. Isto se deve ao fato de o modelo ser orientado a somente um dos outputs, o de soma constante. O modelo teórico desenvolvido é exemplificado a um problema de concessão de descontos e sobretaxas em tarifas aeroportuárias.
