A multi-objective optimization for green supply chain network design

In this paper, we study a supply chain network design problem with environmental concerns. We are interested in the environmental investments decisions in the design phase and propose a multi-objective optimization model that captures the trade-off between the total cost and the environment influence. We conduct a comprehensive set of numerical experiments. The results show that our model can be applied as an effective tool in the strategic planning for green supply chain. Meanwhile, the sensitivity analysis provides some interesting managerial insights for firms.

Research Highlights
► We study a supply chain network design problem with environmental considerations.
► We find that supply chain networks with larger capacities exhibits lower total cost and lower CO2 emission.
► Consideration of environmental emissions of supply chain network is more effective and necessary at a higher demand level.
