Dempster-Shafer证据理论在空战态势评估方面的应用

为了准确分析空战态势,以达到辅助决策之目的,采用D-S证据理论对态势进行评估.首先提取出影响空战态势的战术条件,称之为态势因素,然后分析每个因素的影响效果.在此基础上建立态势评估的数学模型,利用D-S合成法则将所有因素的影响进行综合,并计算出态势发生的结果及可能性区间.最后,通过仿真实例验证了该方法在空战态势评估中的可行性和实用性.

Applications of Dempster-Shafer evidence theory in air combat situation assessment

In order to analyze air combat situation accurately and assist for decision-making, the D-S evidence theory is used in air combat situation assessment. The tactical conditions that have effect on air combat situation, called situation factors, are extracted. Then the influence of each factor is analyzed. On which basis, mathematic models for situation assessment are built up. With the D-S composition law, the influences of all factors are integrated, and the results and the intervals in which various situations may take place are calculated out. Examples of simulation showed that the method of situation assessment is feasible and practical in air combat situation assessment.
