Among the important producers and financial organizations in the national economy, the country's major producers, including petrochemicals and refineries, have an important role in improving efficiency and preventing crude oil. In this regard, managers of these organizations are struggling to improve efficiency in light of the economic conditions. The classic approach of data envelopment analysis models takes into account the linear pricing performance for inputs and outputs in the evaluation. In this paper, we examined the efficiency of the top ten petrochemical companies in the year 1395 by modeling with the help of auxiliary variables and nonlinear values of inputs and outputs. An important feature of the proposed model is that it considers nonlinear values of inputs and outputs. In the DEA total analysis, all weights are taken linearly
They can not show the reality of the issue in many practical applications.
