Technological Advancements in Global Supply Chains: A Comparative Analysis of Sustainability in Aerospace and Shipbuilding Industries

The decentralization of production processes organized in global supply chains has made it possible to connect the different levels through industrial digitalization, an evolution derived from the Fourth Industrial Revolution which incorporates enabling technologies. This context raises the need to analyze sectors that, due to the complexity of their projects, require more efficient supply chain management. Two clear examples of these sectors are aerospace and shipbuilding, which demand greater efficiency and sustainability in their operations. The main objective of this study is to compare these two sectors to evaluate the degree of sustainability of their supply chains and how Industry 4.0 technologies have contributed to achieving these goals. To perform this, the Delphi method will be used, a tool that collects information through expert opinions, which will provide key indicators for the comparison. The use of this method will facilitate the identification of convergences and divergences in the management of sustainability in both sectors. Through this analysis, the expected results will reflect the specific needs of each industry in terms of productivity and sustainability. Thus, the study will offer a comprehensive view of how the aerospace and shipbuilding sectors can move toward more sustainable and efficient production models, integrating Industry 4.0 concepts and improving the management of their global supply chains.
