  Data envelopment analysis based on mathematical programming for decision-making units determines the efficiency score in addition to the projection of inefficient DMUs on the efficient frontier. Centralized Allocation Resource (CRA) with a two-stage linear programming model captures the projection of ...  Read More

Additive slacks-based measure of efficiency for dealing with undesirable outputs based on DEA-R model

Javad Gerami; Mohammad Reza Mozaffari

Volume 1, Issue 1 , March 2021, , Pages 15-23


  In this paper, we present an Additive Slacks-Based Measure (ASBM) model for measuring efficiency Decision-Making Unit (DMU) in the presence of undesirable outputs based on DEA Ratio based (DEA-R) model. In order to obtain a reasonable measure of efficiency, this paper proposes a concept for determining ...  Read More
