Application of Fuzzy TODIM Aligned with the SCOR Model to Identify and Rank Green Supply Chain Strategies

The present study developed and prioritized green supply chain strategies with uncertainty over time under fuzzy conditions in Mobarakeh Steel Company. First, the internal strengths, weaknesses, opportunities, and threats were identified based on theoretical foundations and experts’ opinion. Then, the green supply chain strategies of Mobarakeh Steel Company were developed using the SWOT method. Fuzzy ANP method was used for weighing the dimensions of sustainability while the TOPSIS and TODIM methods were used for weighing the strategies. The results indicated that among the indicators of sustainability, "economic" indicator had the first rank, "environmental" indicator had the second rank, and "social" indicator had the third rank. In addition, SO strategies had the first rank, ST strategies had the second rank, WO strategies had the third rank, WT strategies had the fourth rank. By calculating total performance according to SCOR DEA model, in SCOR supply chain network, the Mobarake steel of Isfahan have the highest performance and Arin Folad of Isfahan have the lowest performance. A big difference was observed between the performance level calculated by the DDEA method and the performance calculated by DEA, in some cases, the performance calculated by the DEA method is lower than that calculated by the DDEA method. The average calculated performance in the DEA method is equal to 0.78 and the mean for the DDEA method is 0.83.
