Computation of Congestion in DEA Models with Productions Trade-offs and Weight Restrictions

Our aim in this work is to determine congestion with productions trade-offs or, equivalently, under weights restrictions in data envelopment analysis (DEA). For this purpose, we review a two-model approach to evaluate congestion (Cooper et al, 1996), and after that we have brief view in relation with computation of efficient targets with production trade-off in Podinovski’s procedure (Podinovski, 2007a). So, our method is a hybrid of two above procedure: computation of congestion with weight restrictions which is supported by an experimental example (Podinovski, 2007b).
