The document discusses Altair's Optimization Centre delivery model. It provides an environment and culture for developing optimization processes and best practices. The Optimization Centre relieves pressure from design teams by focusing on weight reduction and performance balance. It is structured as a center of excellence staffed by a multidisciplinary project team facilitated by integrated software tools and processes. The document also provides examples of Bombardier and MC-21 aircraft programs supported by Optimization Centres, including structural optimization, trade studies, and virtual testing activities.
