Abstract
Increasing social awareness has raised expectations for companies to embrace their social responsibilities. Corporate social responsibility (CSR) is the concept that organizations take into account the interests of society through being responsible for the impact of their activities on customers, suppliers, employees, shareholders, and the broader community and environment in which they operate. This commitment goes beyond legal obligations, whereby organizations take meaningful steps to improve the quality of life of employees, customers, and other stakeholders. However, limited research has focused on integrating sustainability and corporate social responsibility in supplier selection literature. This research presents a group multi criteria decision making model to evaluate and rank contractors based on social responsibility criteria. This evaluation examines social responsibility from various dimensions of moral responsibilities, societal responsibilities, environmental responsibilities, and commitments to employees and customers. The proposed model is applied in a real case study at Shazand Petrochemical Company. The suggested approach is to develop a fuzzy analytical hierarchy process technique using fuzzy Z numbers. The key advantage of using fuzzy Z numbers in multi-criteria decision-making is the possibility of considering the confidence levels of various decision-makers in the calculations. Therefore, the proposed technique can be easily applied in developing other multi-criteria techniques as well as other applications that deal with diverse groups of experts with varying degrees of confidence. The results can help the organization in selecting socially responsible suppliers, and in this way helping in the achievement of sustainability goals and enhancing the company's competitiveness and reputation.
