【摘要】：总体部是我国重大航天工程设计过程中采用的一种创新性的方案设计模式,其对工程主要分系统进行总体设计的思想及优化控制方式与传统的分散独立设计模式完全不同。在考虑了分系统复杂相关性的方案设计框架下,构建了总体部和分散独立方案设计模式的系统设计模型。与分散独立方案设计模式下的Nash均衡不同,总体部模型的均衡解是Stackelberg-Nash均衡。还应用基于Agent的仿真方法比较了总体部和分散独立方案设计模式的均衡状态和绩效。仿真结果证明,总体部方案设计模式既有助于避免系统设计方案陷入某些分系统的局部最优解,也有助于提高系统的整体设计绩效。并且,在总体部方案设计模式下,采用顺序的设计策略有助于提高系统方案的均衡稳定性和绩效,即先由总体部门优化重要分系统的设计方案,再分散搜索剩余分系统的设计方案。本研究证明了总体部方案设计模式在重大航天工程系统方案设计中的有效性,有助于"综合集成"方法的发展和应用。
[Abstract]:The general department is an innovative scheme design pattern used in the design process of major aerospace engineering in our country. The idea of overall design and optimization control mode of the main subsystems of the engineering are completely different from the traditional decentralized independent design mode. The system design model of the overall part and the decentralized independent scheme design pattern is constructed under the framework of the complex relativity of the subsystem. Different from the Nash equilibrium in the decentralized independent scheme design mode, the equilibrium solution of the global partial model is the Stackelberg-Nash equilibrium. The simulation method based on Agent is also used to compare the equilibrium state and performance of the overall part and the decentralized independent scheme design pattern. The simulation results show that the overall design pattern can not only avoid the system design scheme from falling into the local optimal solution of some subsystems, but also improve the overall design performance of the system. Moreover, in the overall department scheme design mode, the use of sequential design strategy is helpful to improve the equilibrium stability and performance of the system scheme, that is, to optimize the design scheme of the important subsystem by the overall department. Then decentralized search for the remaining sub-system design. This study proves the effectiveness of the overall scheme design pattern in the design of major aerospace engineering systems, and is helpful to the development and application of the "integrated integration" method.
