Estimation of Return to Scale under Weight Restrictions in Data Envelopment Analysis
Abstract:   (6576 Views)
Return-To-Scale (RTS) is a most important topic in DEA. Many methods are not obtained for estimating RTS in DEA, yet. In this paper has developed the Banker-Trall approach to identify situation for RTS for the BCC model "multiplier form" with virtual weight restrictions that are imposed to model by DM judgments. Imposing weight restrictions to DEA models often has created problem of infeasibility the DEA models. Thus, the proposed models via Estellita Lins et al. (2006) are applied for testing feasibility weighted BCC model and to provide minimally acceptable adjustments to original restrictions that render the weighted model feasible.
