We have carried out an exhaustive review of the site contracts and flows for all its activities (mechanical, optical, thermal, electrical), integrating the logistical constraints specific to the sector of activity (space). Together with the local operational teams, we have developed a logistics diagnosis based on process, performance, quality and competence. Then, we worked with the central teams to converge the logistics scenarios: multi-site regional hub versus dedicated hub for the site, degree of transport sharing, use of existing infrastructures or use of an external service provider… Quantitative and qualitative analyses were carried out to recommend a target scenario.
