The AFIS Academy-Industry meetings were organized on 4-6 December 2018 in Nancy at the University of Lorraine. They brought together up to 165 participants in 6 complementary events: the Preforum at the LF2L-ENSGSI, the RobAFIS 2018 competition at the Faculty of Science and Technology, the 8th AFIS Academy-Industry Forum 2018, the Doctoral Seminar 2018, the AFIS Thesis Prize 2018, the celebration of the 20th anniversary of AFIS and the Gala Dinner of the Forum with the theme "AFIS celebrates its 20th anniversary"! These meetings provide opportunities for exchanges between academic and industrial communities on the theme of Systems Engineering, its industrial implementation, teaching and related research issues. The unifying theme chosen for this edition was: From the complexity of systems to their acceptance and ease of use. This theme is linked to the expertise, teaching and research in Systems Engineering, developed by the teachers-researchers of the University of Lorraine, organizers of these events. This theme is stated in the form of a paradox, a challenge faced by manufacturers in a context of change from a product economy to a service or even experience economy. How to design systems to control their complexity and ensure simplicity/acceptance of uses? How are Systems Engineering processes and methods impacted by this rationale, how can Systems Engineering facilitate this transition within companies?
