Abstract

In this paper, a methodology is proposed to measure the efficiency of
national energy sector in IRAN. The technical and environmental
performance of the oil refineries in IRAN as a major producer of energy and
fuel are evaluated based on data from years 2010 to 2013. In this study, a
fuzzy multi-objective multi-period common weight network data
envelopment analysis approach is proposed and customized to evaluate the
performance of oil refineries. A certain scenario, called food-production in
which a refinery is assumed as a decision making unit (DMU) consuming
inputs to produce outputs, is considered to evaluate the technical and
environmental performance in presence of undesirable outputs. The main
contribution of this study are summarized as: (1) Proposing a multiobjective
common weight DEA model in order to determine the weights of
inputs and outputs in a single run; (2) Calculating the long term efficiency
scores during a multiple-periods of planning incorporating dynamic nature
of inputs and outputs; (3) Handling a compromise solution using fuzzy
mathematical programming to address multi-objective mathematical
programming; (4) Proposing a linear mathematical programming to achieve
the global optimum solutions; (5) Enhancing the discrimination power of the
DEA models; (6) Reducing the computational time of modeling and solution
procedure; (7) incorporating effective criteria in the modeling procedure.
The analysis of case study presents the efficacy and applicability of
proposed method in comparison with existing classic models.
