以地面合成分队联合作战为背景, 建立了基于集群目标的威胁评估指标体系; 针对传统威胁评估方法中采用常权权重易导致状态失衡的问题, 引入区间数理论确定指标区间常权, 并结合作战态势利用变权理论确定指标区间变权权重, 使权重能够随着战场变化而动态调整; 将区间变权与灰色关联法相结合, 构建出一种适用于区间数的最小二乘灰色关联威胁评估模型。最后通过实例仿真验证了模型和方法的有效性。

In the background of the joint operations of ground synthetic units, a threat assessment indicator system based on cluster targets was established. Aiming at the problem of the imbalance of state in the traditional threat assessment method caused by invariant weight, the interval number theory was introduced to determine the index interval invariant weight, and the variable weight theory was used in combination with the combat situation to determine the index interval variable weight, so that the weight can be dynamically adjusted with the change of the battlefield. By combining interval variable weight with grey correlation method, the least-squares grey-correlation threat assessment model for interval number was constructed. Finally, the effectiveness of the model and the method was verified by the example simulation.
