Sustainable Supply Chain Network Design Considering the Interactive Influence of the Multiproduct on the Production Capacity

Multiproduct supply chain network design has been a hot and important issue in the field of operational and management science. In literature, the interactive influence on the production capacity of different types of products is ignored. As a result, the plan obtained by the optimization model is not effective in practice. In this study, the different productivities for different types of products are considered, and some new production capacity constraints are introduced. Based on these constraints, a multi-objective optimization model is developed to solve the supplier selection and production planning problems. Both economic and environmental performances are considered in this model. The objectives are to minimize the total cost and carbon emissions. Finally, a case study about a multiproduct supply chain network is performed to validate the model proposed. In the future research, more experiments will be designed to compare the difference between optimization with and without consideration of the environmental objective and the interactive influence of multiproduct.
