基于模型的无人机系统架构综合评估方法

系统架构综合评估是无人机(unmanned aerial vehicle, UAV)研制中的重要环节，本文从UAV总体设计的需求出发，提出了系统架构综合评估指标体系的全面性和层次性原则。根据基于模型的系统工程方法构建了三级评估指标体系。通过将系统架构模型的仿真结果作为评估指标体系的输入，建立了一种系统架构模型与评估模型关联的综合评估分析方法，以达到UAV总体技术方案快速闭环设计与优化的目标。面向工程应用，开发了一个系统架构多方案权衡软件。以某UAV系统架构综合评估作为实例，验证了方法与工具的正确性和工程实用性。

Model-based integrated evaluation of UAV system architecture

Integrated evaluation of system architecture is an important phase in unmanned aerial vehicle (UAV) development. Based on the conceptual and preliminary design requirements of UAV, the comprehensive and hierarchical criteria of the integrated evaluation measures relationship of the system architecture are established. According to the model-based systems engineering approach, three-level evaluation measures system is constructed. By using the simulation results of the system architecture model as the input of the evaluation measure, the integrated evaluation and analysis method of seamless connection between the system architecture model and the evaluation model is established to meet the needs of rapid closed-loop design and optimization for the conceptual and preliminary solution of UAV. Facing engineering applications, system architecture trade-off software is developed. Taking the integrated evaluation of UAV system architecture as an example, the correctness and practicability of the method and the tool are verified.
