Introduction: Given the competitive nature of the production market, companies pay special attention to supply chain management to enhance their competitiveness. Today, due to increasing consumer awareness and environmental demands from diverse global markets, industries are focusing more on supply chain sustainability. The starting point for achieving sustainability in the supply chain is the selection of suppliers based on sustainability principles. Consequently, sustainable supplier selection, which forms a critical part of supply chains, has become a vital strategic decision for companies aiming to achieve sustainable development and gain a competitive advantage. The purpose of this study is to identify the most important sustainability indicators and evaluate and select suppliers in the pharmaceutical supply chain based on their sustainability performance.
Methods: This research is applied in terms of purpose and is classified as descriptive-analytical in terms of methodology. In this study, a new hybrid approach combining fuzzy Multi-Criteria Decision-Making (MCDM) and fuzzy Data Envelopment Analysis (DEA) was used to select suppliers. The proposed approach was implemented in Sobhan Darou Company as a case study. Initially, a list of criteria was identified through a literature review and finalized using the fuzzy Delphi method. Then, the fuzzy DEMATEL method was employed to assess the mutual influence and interdependencies among the criteria. In the next stage, the fuzzy Analytical Network Process (ANP) was used to determine the importance of the dimensions and criteria. Finally, the efficiency of suppliers was determined using fuzzy DEA, and the top-performing suppliers were identified.
Results and discussion: According to the research findings, 33 initially identified criteria were screened using the fuzzy Delphi method, resulting in 15 final criteria across four dimensions: economic, environmental, social, and services, which were confirmed by experts. The results of the fuzzy DEMATEL method indicated that the criterion "Commitment to the Development of Environmental and Energy Management Systems" was the most influential, while the criterion "Pollution Control Initiatives and Effective Waste Management" was the most affected. Additionally, the economic and environmental dimensions had the highest influence within the system, while the social and service dimensions were the most affected. According to the results of the fuzzy ANP method, the criteria "Quality of Raw Materials and Packaging," "Commitment to the Development of Environmental and Energy Management Systems," and "Investment in Green Research and Development" were identified as the most important criteria for supplier evaluation. Among the dimensions, the economic and environmental dimensions were found to be the most significant. Based on the final ranking of the fuzzy DEA model, 15 suppliers of Sobhan Darou were ranked based on their efficiency, with suppliers 1, 6, and 2 ranking first to third, respectively.
Conclusions: The results indicate that managers and experts in pharmaceutical companies, including procurement and purchasing managers, should pay special attention to economic and environmental indicators when evaluating and selecting sustainable suppliers. Furthermore, the managers of Sobhan Darou Company can establish long-term contracts with suppliers 1, 6, and 2, which have demonstrated strong performance. These findings not only help pharmaceutical companies select the best suppliers but also allow other industries to improve their supplier selection processes using this hybrid model.
