Aero systems continuously increase in complexity, while security, safety and certification requirements impose strong controls on the design and verification/validation of these systems. The Product Lifecycle of an aero system is composed of several processes that include hundreds of tools and thousands of artifacts (data, software, models). The lack of interconnection and traceability of these artifacts is a major factor for delays and/or cost run-overs; tackling the problem of digital discontinuity is a major issue in the industry. Moreover, data-driven analyses are increasingly used during the design process and they call for this discontinuity to be further addressed. In this talk we see how to leverage knowledge engineering methods and technologies for addressing these problems.
