Treffer: A comprehensive blockchain-enabled supply chain network design: an iterative model versus an integrated model.

As an outcome of economies of scale, demand growth can benefit companies in various ways. However, demand fulfillment and management are just not possible in a supply chain whose managers focus only on cost minimization. For this reason, the present paper proposes a sustainable, efficient, customer-centered and resilient closed-loop supply chain network. Limited access to labor during the Covid-19 pandemic, traffic congestion due to transportation of products, as well as transparency through the Blockchain technology are some of the key considerations in our supply chain network design. To the best of our knowledge, this is the first attempt where such a supply chain network is designed, solved and analyzed based on iterative and integrated models. The fuzzy goal programming is adopted as a solution approach for both of the proposed models. The applications of the proposed models are demonstrated in the context of a case study. Furthermore, the results showed that the iterative model can focus on the expenditure minimization strategy and the integrated model can focus on the transparency and efficiency strategies.
