摘要：In order to take requirements for commercial operations or military missions into better consideration in new flight vehicle design, a tri-hierarchical task classification model of ＂design for operation＂ is proposed, which takes basic man-object interaction task, complex collaborative operation and large-scale joint operation into account. The corresponding general architecture of evaluation criteria is also depicted. Then a virtual simulation-based approach to implement the evaluations at three hierarchy levels is mainly analyzed with a detailed example, which validates the feasibility and effectiveness of evaluation architecture. Finally, extending the virtual simulation architecture from design to operation training is discussed.

摘要：In order to obtain optimized flight vehicle concepts which meet system of systems （SOS） operation requirements, designers have to pay high attention to the impact of SoS at conceptual design stage since operation environment goes increasingly complex. Based on this tendency, per- spectives and progre,;ses of SoS oriented flight vehicle conceptual design, which is abbreviate as SoSed design, are reviewed in this paper. Such basic concepts of SoS as definition, characteristics, differences between systems engineering and SoS engineering, as well as SoSed design process are introduced, then SoS engineering process model for research and development of flight vehicles and SoSed design wheel model for conceptual design are proposed. Related literature is classified and analyzed in accordance with four major elements including requirements, design concept, design analysis, and trade studies and optimization： typical SoS architectures, description and quan- tization of indexes are introduced; Application of inverse design in designing concept is analyzed; Modeling and simulation （M＆S）-based methods and their applications in SoSed effectiveness evaluation are highlighted; According to SoSed trade studies and optimization related research, the importance of such points as decision-making and using multidisciplinary design optimization for reference are emphasized. Finally, the value of SoSed design is concluded, and five directions which are worthy of .attention in this field are presented.

摘要：为了通过客机的市场分析与总体设计的紧密结合进行关键设计指标的更充分的权衡,提出了从航线网络体系的视角进行指标集效能评价的方法。这一方法以燃油效率作为经济性评价准则,基于运营统计数据建立综合考虑航线航程概率及航线实际乘客数概率的运输周转量概率密度分布,结合客机运行空重的估算,计算出各条航线消耗的燃油重量,进而通过多轮次的仿真分析出不同指标集对应的燃油效率概率密度。分析结果有助于权衡各个指标集的潜在设计方案适合在何种航线上运营,以及从燃油效率的角度分析潜在设计方案对航空公司的吸引力。通过在一个算例中对航程和载客量的变化进行计算和分析,说明了所提方法的应用方式,最后对目前研究的局限之处和后续的研究方向进行了探讨。
