舰艇编队动态防空威胁的直觉模糊决策方法

针对舰艇编队在不确定海战场环境中的威胁估计问题,提出一种动态防空威胁的直觉模糊决策方法.首先对来袭目标的不同类型信息作规范化处理,得到直觉模糊决策矩阵;其次由直觉模糊熵权法得出评估指标的初始权重,并融合指挥员的主观偏好信息建立指标权重优化模型,使得权重结果更为合理;然后采用正态分布方法处理多时刻信息,得到不同时刻的权重;最后基于 TOPSIS 思想得到目标的威胁度排序结果.仿真实例表明:该算法具有可行性,为解决舰艇编队的威胁估计问题提供了一种有效的途径.

Dynamic Method for Threat Evaluation in Aerial Defense ofWarship Formation Based on Intuition Fuzzy Decision-making Method

Aiming at the problem of threat evaluation of warship formation in uncertain marine battlefield environment, a dynamic decision-making method based on intuition fuzzy sets is proposed. Firstly, the information in different types of air targets is standardized and intuition fuzzy decision-making matrices can be gained. Secondly, the initial weights of evaluation indexes are computed by using intuitionistic fuzzy entropy and an optimization model combining subjective preference information of commander is established to get more reasonable weight results. Then, time series weight is obtained to handle multi-moments data basing on normal distribution. Finally, on the basis of TOPSIS, levels of threat the raiding targets pose can be assessed and sequenced. A simulation example illustrates the feasibility of the proposed method which provides an effective way to solve the problem of threat evaluation of warship formation.
