Optimisation of multi-objective supply chain networks considering cost minimisation and environmental criteria

Abstract

This article considers the optimisation problem of a multi-objective mass-consumption supply chain network considering cost minimisation and environmental criteria, as well as the analysis of scenarios with variable demand. This study seeks to determine the closure and consolidation of distribution centres and the identification of product flows in the network. The efficiency of the mathematical model has been tested with real information obtained from a Colombian multinational company manufacturing products of mass-consumption. The results confirm the efficiency of the model and its positive impact on determining the environmental impact of gas emissions related to the type of transportation used and the appropriate cost for the case study company.
