无人作战飞机经济寿命正向设计优化建模与求解研究

Aiming at the problems of insufficient theoretical model Support and deficient cost design method for product life cycle in the economic life design of unmanned combat aircraft, the forward design concept and optimization model of economic life of unmanned combat aircraft are proposed. A mixed integer programming selection model is constructed to assist the decision-making of the selection scheme and System life design of each module of the unmanned combat aircraft System, so that the average life cycle cost of the System in the unit use time is optimized. The conceptual model of economic life is applied to the selection stage of unmanned combat aircraft System through Simulation examples, and the forward design of economic life of unmanned combat aircraft is carried out and the economic life selection model is solved. The computation example analysis results show that the proposed optimization model reduces the economic life of the unmanned combat aircraft by 1/5 compared with the design life of the airframe structure and improves the economic efficiency of its life cycle, which verifies the practicability of the proposed model.
