A Three-level Sustainable and Resilient Supply Chain Network Design under Disruption

oday supply chain management is emerging in a new dimension by having the sustainability as its primary focus, but in reality, however, facilities and the links connecting them, disrupt from time to time due to poor weather, natural or man-made disasters, or a combination of any other factors. Due to these unexpected disruptions, supply chain system drop its sustainability while coping with them. Now, the new challenges for the supply chain managers are to design an efficient and effective supply chain network that will be resilient enough to bounce back from any disruption and also should have sufficient vigilance to offer same sustainability under disruption state. Out of three pillars of sustainability namely ecological, social and economic sustainability, this paper is focusing more on the ecological sustainability because environmental focus in supply chain system is more important and also link with other pillars as the products need to be produced, packed and transported in an ethical way which should not harm social balance and environment. Owing to importance of the issue, this paper attempts to introduce network optimization model for sustainable and resilient supply chain network. The proposed goal programming (GP) model optimizes the total cost while considering the resilience and sustainability of the supply chain network.
