Data Envelopment Analysis in Three-Stage Network Structure with Slack Based Measure (SBM)

Data envelopment analysis (DEA) is a non-parametric technique for measuring and analyzing the relative efficiency of Decision-Making Unit (DMU) having multiple homogeneous types inputs outputs. Traditional DEA treats DMU as black boxes calculates their efficiencies by considering initial final But overall directly depended upon performances intermediate processes operations. In many situations, DMUs have three-stage network structure. Against aforesaid backdrop, this paper introduces non-oriented non-radial slacks-based measure (SBM) framework production process. proposed model we considered both series parallel relationship between outputs different independent dependent stages. Additionally, research aimed at Indian banking using model.
