摘　　要：针对对地攻击无人机自主能力量化评价的不确定性问题,提出基于组合赋权的云模型评价方法。基于认知控制结构,从感知探测、规划决策、作战执行、安全管理和学习进化5个方面构建自主能力评价指标体系。运用基于博弈论的组合赋权方法,结合改进层次分析法和改进熵权法确定组合权重,克服了单一赋权方法确定指标权重的片面性。考虑自主能力评价过程的模糊性和随机性,提出一种对地攻击无人机自主能力云模型评价方法,采用浮动云算法实现评价指标云的有效综合。对3种对地攻击无人机进行仿真验证,结果表明:所提方法综合考虑评价对象的主客观因素,消除了单一赋权方法的局限性,权重分配科学合理。自主能力云模型量化评价能够有效区分不同类型对地攻击无人机自主能力等级的差异性,评价结果准确可信。To address the uncertainty in quantitative evaluation of autonomous capability of ground-attack UAVs,an evaluation method with the cloud model is proposed based on combined weightings.Based on the cognitive control structure,the evaluation index system of autonomous capability is constructed from five aspects:perceptual detection,planning and decision-making,combat execution,security management,and learning evolution.The one sidedness of determining the index weight by a single weighting method is overcome,using the combination weighting method based on game theory,and combined with the improved analytic hierarchy process and the improved entropy weight method to determine the combination weight.Considering the fuzziness and randomness of the autonomous capability evaluation process,an evaluation method based on cloud model is proposed for the autonomous capability of ground-attack UAVs,and the floating cloud algorithm is used to realize the effective synthesis of the evaluation index cloud.The simulation results of three ground-attack UAVs show that the proposed method considers both subjective and objective factors of the evaluation object,eliminates the limitations of a single weighting method,and achieves scientific and reasonable weight distribution.The quantitative evaluation of autonomous capability of the cloud model can effectively distinguish autonomous capability levels of different types of ground-attack UAVs,with accurate and reliable evaluation results.
