ABSTRACT

Due to the increasing awareness of environmental and social issues, many practitioners and researchers have paid much attention to the sustainable supply chain management (SSCM) in recent years. Sustainable supplier selection is one of the most critical activities in the SSCM which can affect supply chain performance. However, the previous literature rarely considers the interrelationships between economic, environmental, and social evaluation criteria in the supplier selection. Moreover, the effect of the criteria importance on the criteria interrelationships is scarcely discussed in previous researches. To deal with these problems, a novel integrated methodology is developed in this paper. The proposed method integrates the merit of pairwise comparison method in determining relative importance, the strength of decision making trial and evaluation laboratory (DEMATEL) in manipulating the complex and intertwined problems with fewer data, and the rough number's advantage in flexibly dealing with vague information. A case study in a solar air-conditioner manufacturer is provided to show the feasibility and effectiveness of the proposed methodology.

4. Results and discussions

To validate the applicability and effectiveness of the proposed approach, we apply it in a solar air-conditioner manufacturing company. Company G is a multinational corporation that provides various solar air-conditioning systems and solutions throughout the world. It has been under scrutiny to achieve sustainable supply chain by the stakeholders and customers. Although the company has invested resources in sustainable supply chains, there is still lack of consensus among the managers about the importance of the criteria for sustainable supplier selection. Besides, managers of this company expect to explore interrelationships between different criteria to discern the potential areas for further sustainability improvement. In this respect, the developed methodology is applied in this case study to evaluate and analyze sustainable supplier selection criteria as well as extract their interrelationships.
