SUSTAINABLE CLOSED-LOOP SUPPLY CHAIN MODELING WITH NEUTROSOPHIC PARAMETERS FOR THE HOME APPLIANCES INDUSTRY (REFRIGERATORS AND FREEZERS)

Abstract

With growing concerns over environmental and social issues, the concept of sustainability has become a key pillar in the design and management of supply chains. In this context, closed-loop supply chains, aimed at reducing waste, recycling resources, and creating added value through circular processes, have gained special importance. This study aims to develop a mathematical model for designing a sustainable closed-loop supply chain in the home appliances industry (refrigerators and freezers). The proposed model considers three dimensions of sustainability, including cost, environmental impacts, and social indicators, and employs neutrosophic theory and trapezoidal neutrosophic fuzzy sets to manage uncertainties and ambiguities in the data. To solve the model, a genetic algorithm in the MATLAB environment is utilized. The results indicate that integrating the neutrosophic approach with closed-loop modeling can lead to more effective and sustainable decision-making in the supply chain of the home appliances industry. This model can serve as a practical tool for managers and decision-makers in achieving sustainable development goals and enhancing resource efficiency.
