Aircraft system MBSE manufacturing process optimization method based on improved SPEA2

Civil aircraft development has developed rapidly under the guidance of the model based systems engineering (MBSE) method. As an important link in the development process of civil aircraft, the complexity of civil aircraft system manufacturing has been increasing. In the process of civil aircraft system manufacturing process highlights the long manufacturing cycle, resource consumption and other practical problems. Aiming at the above problems, firstly, the complex relationship between the manufacturing processes of MBSE civil aircraft system is analysed, and a mathematical optimization model of the manufacturing process of civil aircraft system is established. Secondly, in order to take into account the convergence of the algorithm and the diversity of the solution set, an improved SPEA2 algorithm (strength pareto evolutionary algorithm 2, SPEA2) is designed, and a neighbourhood search method based on the density of the solution region and a fuzzy adaptive genetic operator dynamic adjustment method are proposed. Finally, the airborne flat view display system is analysed as an example to verify the effectiveness of the improved algorithm in terms of convergence and diversity. The validation case shows that the proposed method can effectively improve the efficiency and reduce the resource consumption of civil aircraft system manufacturing, and achieve the optimization of the manufacturing process of MBSE civil aircraft system.
