Abstract:

We consider conceptual design problem of a family of aircrafts of different capacities yet having maximum number of elements in common to reduce maintenance and operational costs. Each family member has its own operational requirements and cost criteria, which makes the family selection a multi-criteria equality constrained optimization problem. The conceptual design task supplemented with semi-empirical models for geometry, aerodynamics, weights and performances is successfully solved using MACROS software developed by DATADVANCE. We managed to greatly improve considered performance measures and quantitatively describe the whole variety of optimal non-dominated solutions.
