Abstract
Supplier selection plays an important role in the supply chain management and traditional criteria such as price, quality, and flexibility are considered for supplier performance evaluation in researches. In recent years sustainability has received more attention in the supply chain management literature with triple bottom line (TBL) describing the sustainability in supply chain management with social, environmental, and economic initiatives. This paper explores sustainability in supply chain management and examines the problem of identifying a new model for supplier selection based on extended model of TBL approach in supply chain by presenting fuzzy multicriteria method. Linguistic values of experts' subjective preferences are expressed with fuzzy numbers and Neofuzzy TOPSIS is proposed for finding the best solution of supplier selection problem. Numerical results show that the proposed model is efficient for integrating sustainability in supplier selection problem. The importance of using complimentary aspects of sustainability and Neofuzzy TOPSIS concept in sustainable supplier selection process is shown with sensitivity analysis.

Summary
Sustainability is becoming to play an important role in supply chain management. Companies are increasingly expected to extend their sustainability efforts beyond their own operations to include those of their suppliers and to meet their customers’ sustainability expectations. Organizations consider criteria such as price, quality, flexibility, and delivery when evaluating supplier’s performance In this way companies need efficient ways to select their suppliers with regard to their sustainability policies. Given the multiple criteria nature of sustainable supplier selection problem, we propose a multicriteria method in order to evaluate sustainability performance of a suppliers based on extending TBL theory. The main contribution of this paper includes modelling the supplier selection decision problem within the context of International Scholarly Research Notices a sustainable supply chain based on extended triple bottom line (TBL) concept. The paper is organized as follows; the section is a review of the related literature for sustainability in supply chain management and supplier selection by identifying the sustainability criteria that influence a company’s decision in supplier selection and collaboration process. Efficiency of proposed model is shown with the numerical example and, in the last section, summary and conclusion are provided
