基于AHP-CRITIC组合赋权的VIKOR空战威胁评估

A VIKOR Method for Threat Assessment in Air Combat Based on AHP-CRITIC Combination Weighting

针对在设置空战威胁评估指标权重时,无法完全体现威胁评估数据的客观性以及主观赋权方法对确定权值所带来的主观影响等问题,提出了一种运用AHP方法与CRITIC方法相结合的赋权方法。通过利用AHP方法综合专家对指标权重的判断,再根据CRITIC方法确定客观数据间的联系,实现对威胁评估指标的组合赋权;然后利用VIKOR方法,通过实例仿真进行空战威胁评估;最后,考虑不同决策者主观偏好,设置不同VIKOR方法属性值,得到不同目标威胁评估结果,进行对比分析。通过仿真验证证明该方法具有一定实用性。

When setting the weights of the indexes of threat assessment in air combat,the objectivity of threat assessment data can’t be fully reflected,and the subjective weighting method will affect the results of weight determination.To solve the problems,a weighting method combining the AHP method with the CRITIC method is proposed.The method uses the AHP method to synthesize the experts’judgment of index weights first,and then determines the relationship between the objective data according to the CRITIC method,so as to realize the combination weighting of threat assessment indexes.Then,the VIKOR method is used to assess the threats in air combat through the simulation of an example.Finally,taking into account the subjective preferences of different decision makers,the method sets different attribute values of the VIKOR method to obtain different results of target threat assessment for comparative analysis.The simulation results show that this method has certain practical values.
