In the most recent years, industry has been touched by the simultaneous introduction of 4.0 smart technologies and new elements of complexity mainly related to mutated interactions between humans and machines. This change has made the issue of safeguarding safety and reliability an increasingly central and challenging topic. At the same time, complex industrial systems need to be resilient, that is able to absorb shocks and facing changes or uncertainties, through adequate reaction and adaptation.

Technologies introduced by Industry 4.0 can increase workers safety and improve reliability and resilience of processes against system failures. However, new technologies have also introduced unexpected risks. Identifying critical components of an industrial system and considering its different elements with their dependencies can allow to balance safety advantages and risks while keeping resilience ability.

In the present study, the main 4.0 technological solutions for safety, their possible contraindications and the corresponding effects on the resilience capacity of the overall system are described and considered as distributed all along a specific company multi-level representation. The elements in the proposed model are firstly detailed for every identified company level; then, results are also synthesized in table form.

Keywords: Resilience, Complexity, Safety, Industry 4.0, Smart technologies, Risk.
