Abstract:

Development Assurance Level (DAL) assignment is an important task in the process of aircraft system development. It is usually required to minimize development costs on the basis of satisfying the DAL assignment principles. A multi-objective optimization model for DAL assignment is constructed. The DAL assignment principles and the top-level failure condition probability requirement are taken as qualitative and quantitative constraints, respectively. The optimization objectives are the minimization of development cost and system weight. The DALs assigned to functions or items in the system are taken as decision variables. Besides, a method for DAL assignment is proposed based on the multi-objective artificial hummingbird algorithm. A case study is given based on a fly-by-wire system, and a non-dominated solution set for DAL assignment is obtained. Under the same test condition, the proposed method reduces the execution time by 17.59% and improves the HV metric by 63.49% compared with multi-objective particle swarm optimization, which indicates that the proposed method can converge quickly and the obtained solution set has good distribution.
