[ 1 ] - Cost Efficiency Evaluation via Data Envelopment Analysis Approach for Undesirable Outputs based on the Weak Disposability Axiom (Case Study: 56 Electricity Producing Thermal Power Plants in Iran)

Cost efficiency evaluation is a very important and applicable issue in Data Envelopment ‎Analysis (DEA). In this paper, the classical cost efficiency model in which all the input ‎prices are known and fixed for each decision making unit is developed via undesirable ‎outputs with the weak disposability axiom. The proposed model is a nonlinear model ‎under the variable returns to scale condition,...
