摘　　要：针对防空雷达选址影响因素较多所造成的决策过程计算复杂度高的问题,提出一种基于决策门限改进的层次分析法(AHP)模型,用以降低计算资源开销和决策处理时延。首先,建立防空雷达选址的层次分析模型,通过构造判断矩阵和进行一致性检验定性分析各因素间的相对重要性;然后,设定决策门限筛选主要选址影响因素并更新选址因素的权重;最后,综合评价各因素的权重和其对选址的影响,做出最终的选址决策。仿真结果验证了通过决策门限来改进层次分析是有效的,与未改进的层次分析结果相比,所提方法能够有效降低决策的计算复杂度(约为未改进AHP的0.38~0.75),选址的一致率在不同的门限设置上的都能够超过92%。该方法为层次分析模型的改进和解决选址问题提供了一定指导和参考价值。In order to reduce computational resource overhead and decision processing latency,this paper proposes an analytic hierarchy process(AHP)model with improved decision threshold to address the issue of multiple influencing factors and high computational complexity in the selection of air defense radar sites.Firstly,an analytic hierarchy process model was established for air defense radar site selection,and the relative importance of each factor was qualitatively analyzed by constructing a judgment matrix and consistency testing.Then,decision thresholds was set to screen the main site selection influencing factors and the weights of site selection factors was updated.Finally,the weights of each factor and their impact on site selection were comprehensively evaluated in order to make the final site selection decision.The simulation results have verified the effectiveness of improving the AHP through decision thresholds.Compared with the results of the unimproved AHP,the method can effectively reduce the computational complexity of decision making(about 0.38~0.75 for unimproved AHP),and the consistency rate of site selection can exceed 92%under different threshold settings.In addition,this method provides certain guidance and reference value for improving the analytic hierarchy process model and solving location problems.
