Abstract
In order to solve the problems of existing threat assessment algorithms, a threat assessment method based on intuitionistic fuzzy three-way decision method is proposed. Firstly, the indexes are described by theory of intuitionistic fuzzy sets on the basis of that the threat assessment index system is established. Then, TOPSIS method is used to calculate the target threat. Finally, the targets are classified by three-way decision method according to the result of target threat. It is proved that it is feasible to introduce three-way decision method into threat assessment. At the same time, an improved algorithm for calculating the threshold of three-way decision is proposed. Experiments show that the improved algorithm has stable results and good classification effect.
Highlights
At present, the research on threat assessment of air targets is mostly based on the selection and treatment of threat factors
This paper intends to use the threeway decision method based on intuitionistic fuzzy sets to study the air combat threat assessment and the threat assessment from a new perspective, hoping to provide new ideas and ways to solve the problems in this field
The results show that the improved adaptive threshold algorithm proposed in this paper is stable, has good classification effect, and can overcome the shortcomings of the existing algorithm
Summary
The research on threat assessment of air targets is mostly based on the selection and treatment of threat factors. For targets whose threat value is higher than a certain threshold, they should adopt attack strategy, and for targets whose threat value is lower than that threshold, they should adopt the strategy of abandoning attack This kind of decision-making result is either one or the other, so a two-way decision model may lead to a highcost loss due to the lack of suitable information for making a precise decision. Its core idea is to divide a unified set into three disjoint paired regions: positive domain, negative domain, and boundary domain It provides an effective strategy and method for solving complex problems by formulating corresponding decision-making strategies for each region. This paper intends to use the threeway decision method based on intuitionistic fuzzy sets to study the air combat threat assessment and the threat assessment from a new perspective, hoping to provide new ideas and ways to solve the problems in this field
