Research on Decision-making Division Method of Air Targets Based on Cost Loss Function
Threat level division for air threat targets and assist attack decision-making are pro-vided.Based on the improved VIKOR method and the relationship between loss function and threshold in the three-way decision,the methods of threat estimation and decision-making division are studied.Firstly,the evaluation attributes are analyzed and modeled,and the weights are calculated with the AHP method.Secondly,three-way models are established,and the conditional probability of the target is calculated with the improved VIKOR method to complete the target threat ranking.By combining the relationship between the cost loss function and the threshold parameters in the three-way decision-making model,the method of finding the threshold and the cost loss function is transformed into an opti-mization problem,and the PSO algorithm is used to solve the problem.Finally,based on the obtained threshold,the threat level and decision-making of the target within the domain of discourse are classi-fied.The example analysis shows that this method ensures the minimum threat level and decision-making division cost within a certain range,while taking into account the decision-maker's psychology,the expected target threat assessment results can be achieved.
