Abstract: (451 Views) |
As an important part of the competitive functions of industries, especially parent industries such as petrochemicals, the energy supply chain plays an important role in maintaining the competitiveness and continuous improvement of companies active in this industry, therefore, the evaluation of the pattern of the energy supply chain in the petrochemical industry, using the Malmquist productivity index, Reducing production costs and better evaluating the industry and formulating future policies of companies active in this field can help. First, the input and output of the energy supply chain are identified using the interactive qualitative analysis method, and according to the type of input, a mathematical model is written to estimate the input costs to supply the output and the efficiency of the supply chain in two consecutive years. The Malmquist cost index is estimated according to the outputs of the model, and the petrochemical company that has the highest Malmquist cost index and the lowest output costs is selected as the optimal solution of the model.
