摘要:

作战体系能力图谱是从整体分析作战体系能力的有效方法。针对生成作战体系能力图谱时, 需要对海量实验空间进行仿真而带来时效性较差的问题, 提出一种基于Stacking集成元模型的作战体系能力图谱生成方法。该方法通过建立元模型替代仿真模型, 能够快速准确生成作战体系能力图谱。针对各类元模型适用场景有限、性能波动较大的问题, 提出采用Stacking方法对多种元模型进行集成, 提高不同应用环境下元模型的鲁棒性; 针对建立元模型时精度与效率的矛盾问题, 提出适用于体系能力图谱生成的序贯采样策略, 通过计算拟合不确定性, 选取高价值样本, 在达到相同准确性指标的同时减少采样次数。最后, 通过实验案例分析, 证明了所提方法的有效性。

Abstract:

Operational system of system (SoS) capability graph is an effective method to analyze operational SoS capability as a whole. Aiming at the problem of timeliness caused by the need to simulate the massive experimental space when generating the operational SoS capability graph, a method of generating the operational SoS capability graph based on the Stacking integrated meta-model is proposed. The method generated the operational SoS capability graph quickly and accurately by building the meta-model instead of the simulation model. Aiming at the problems of limited application scenarios and fluctuating performance of various meta-model, the Stacking method is proposed to integrate multiple meta-models to improve the robustness of meta-models in different application environments. Aiming at the contradiction between accuracy and efficiency in the meta-model building, a sequential sampling strategy is proposed for the generation of operational SoS capability graph. By calculating the meta-model uncertainty, high-value samples are selected to reduce the number of sampling while achieving the same accuracy index. Finally, an experimental case analysis proves the proposed effectiveness of the method.

Key words: operational system of systems, capability graph, Stacking ensemble learning, meta-model
