The study of wide-body aircraft family using NSGAII

Recently, there has been a transformation from the single mode to family for the aircraft family design concept. The design method has been studied according to the general criteria to establish a design model for the aircraft family, which considers the economic index (conceptual design and manufacturing cost) and maximum take off weight as the object functions, and the payload as a constrain. The Solution can be obtained by Fast non-dominated sorting genetic algorithmII, before selection 2 schemes from the set and comparing them. The meaningful analytical results also provide the basis for the conceptual design of the aircraft family.
