The design of a sustainable-resilient forward-reverse logistics network considering resource sharing and using an accelerated Benders decomposition algorithm

In recent years, supply chain cooperation has been considered to increase efficiency and reduce costs. In this study, the resource sharing approach is used to design a sustainable-resilient steel supply chain. Also, to cope with uncertainty, a robust optimisation method is applied, and the effects of disruption risk on sustainability indicators, such as damage to workers and job opportunities lost, are considered. A Benders decomposition algorithm with two acceleration mechanisms is customised so that results show algorithm efficiency for solving large-size instances. In addition, the computational analysis shows the proposed strategies to cope with disruption can reduce total costs and increase network sustainability. Finally, managerial insights according to the results of the study are suggested. Hence, this study brings a novel research perspective for collaborative forward-reverse logistics network design.
