Provide a multi-objective mathematical model to achieve a green supply chain to a sustainable supply chain taking into account the social dimension

Organizations have been forced to change attitudes in supply chain management after facing several factors such as rising levels of outsourcing, rising transportation costs, competitive pressures, and globalization. The desire of customers, the pressure of nature-friendly groups, international and governmental organizations that support the environment has caused organizations to pay attention to issues related to environmental management and energy. To solve these problems, green supply chain management was introduced, which aims to minimize waste and emit pollutants along the supply chain. Due to the importance of this issue, in the present study entitled “Presenting a multi-objective mathematical model for green supply chain management to achieve a sustainable supply chain”, an attempt has been made to consider three economic, environmental, and social dimensions of sustainable development. Model and make decisions at the supply chain planning and design level and achieve a sustainable supply chain model. Most studies in the field of the sustainable supply chain have provided general definitions and in case of further modeling, attention has been paid to economic and environmental fields. Therefore, the present study tries to look at the issue with a more comprehensive and practical view and to model and optimize all dimensions of supply chain sustainability. Generally, in the supply chain literature, more research has been done on two dimensions of sustainability (either economic and environmental or economic and social). Articles dealing with all three aspects of sustainability require little research. Also, in such articles, a small number have done mathematical modeling and in this area of literature, combos are felt. This article pays special attention to the third dimension of sustainability, namely social sustainability. Finally, using random data, the model is solved in Gomez and the results are presented in the form of a numerical example. The presented results show that the mathematical model is applied and can be used for real problems and give optimal answers.
