基于多级模糊综合评判法的态势评估方法研究

摘要

态势评估技术是战术辅助决策系统的主要组成部分.为了得到更贴近实战的战术空战态势评估方法,针对现代超视距空战特点,分析影响空战的多个主要因素,建立了二层空战优势模型;然后以改进模糊评判算子和采用多层评判模型为基础,将建立的多因素空战优势函数作为模糊隶属函数,采用多级模糊综合评判法,建立目标与准则的模糊关系,确定空战优势矩阵;采用模糊论域划分的方法进一步分析空战优势信息,最终得到空战优势态势表.实例计算表明,该方法可以有效得出战术空战态势及更加可靠的结果.%Situation assessment technique is the main part of assistant tactic decision-making system. In order to obtain a more suitable air combat situation assessment method, the main factors that have effect on the air combat were analyzed, and a dual-level air combat superiority model was established taking the characteristics of beyond-visual-range air combat into account. Then based on the improved fuzzy judgment operator and multi-level judgment model,the fuzzy relationship between goals and rules was set up and the air combat superiority matrix was established through multi-level fuzzy integration judgment. At last, air combat situation table was obtained after analyzing the air combat superiority message with fuzzy field partition. Calculation result of an example shows that by using the method, the tactic air combat situation can be obtained effectively with more reliable result.
