optimization of a green supply chain network: a case study in a pharmaceutical industry

Green supply chain managementgscm) is defined as the integration of environmental thinking into supply-chain management, including product design, material sourcing and selection, manufacturing processes and procurement. generally, the sustainable supply chain is built on three dimensions: social, economic, and environmental, while the green supply chain emphasizes on the environmental issue considering an economic result. although many works of sustainable growth heed attention on the profit margin as a first priority, however, the green supply chain focuses on the environmental issue along with an efficacious process, which is a beneficial to the environment as well. there are over 200 papers about gscm. but among them, very few papers focus on the pharmaceutical industry, specially focusing on the supplier. but this paper focuses on implementing gscm on pharmaceutical industry. multi-objective optimization model has been applied here. performance of the proposed model is evaluated by the pycharm solver of python.
