Take away
- The AGILE4.0 Framework can be used to succesfully explore the design space and find the Pareto front between family-level Direct Operating Costs (DOC) and OEM Non-Recurring Costs (NRC)
- An increase in the number of components shared generally leads to lower family-level NRC, however at the cost of less efficient aircraft components and therefore higher average DOC.
