Abstract

The invention discloses a ship formation air defense group decision making threat estimation method based on a dynamic intuitionistic fuzzy method. According to the method, first, a dynamic intuitionistic fuzzy multiple attribute group decision making matrix is established; second, a belief function, intuitionistic fuzzy entropy and a normal distribution method are adopted to solve decision makerweights, index attribute weights and time sequence weights respectively, so that weight results are more objective; third, a to-be-evaluated intuitionistic fuzzy multiple attribute decision making matrix is obtained through two times of dimension reduction on the dynamic intuitionistic fuzzy group decision making matrix, so that the complexity of the matrix is lowered, and the operation amount islowered; and last, a VIKOR method is utilized to order threat degrees of coming targets. Through the method, threat evaluation of the air coming targets by multiple decision makers in multiple time periods is mainly realized.

Description

technical field [0001] The invention belongs to the technical field of ship formation threat estimation, in particular to a ship formation group decision-making threat estimation method based on a dynamic intuitional fuzzy method. Background technique [0002] In the air defense command and decision-making of ship formation coordinated operations, the first task faced by ship decision makers is to quickly and accurately determine the threat level of incoming air targets to the ship formation, so as to rationally allocate formation air defense weapon resources and effectively organize firepower. Provides an important basis for striking the target. However, due to the strong mobility, stealth, and aggressiveness of incoming air targets, the battlefield situation changes rapidly in different time segments, and the decision-making environment is full of a lot of uncertainty. At the same time, due to the differences in the performance of various types of sensors, the decision-ma...
