Embodiment Construction

[0023] The technical solutions of the present invention are described in detail with reference to the accompanying drawings.

[0024] A method for estimating dynamic air defense threat of ship formation based on fuzzy intuitionistic TOPSIS of the present invention specifically includes the following steps:

[0025] Step 1 to the incoming target U i (i=1, 2, ..., m) different forms of evaluation index C j The attribute values ​​of (j=1, 2, ..., n) are uniformly normalized into the form of intuitionistic fuzzy numbers, including:

[0026] (1) For qualitative indicators, establish the transformation of linguistic variables to intuitionistic fuzzy numbers, such as figure 2 shown.

[0027] (2) For quantitative indicators in the form of real numbers, first establish the intuitive perception level of the target threat, such as image 3 shown. Let U i About C j The attribute value of x ij , then for the benefit index, we have For cost indicators, there are will r ij and ...

Abstract

The invention discloses a naval vessel formation dynamic air defense threat estimation method based on intuitionistic fuzzy TOPSIS, and relates to the field of naval vessel formation air defense decision. The method comprises the following steps of firstly standardizing different types of target information, and establishing an intuitionistic fuzzy decision matrix; secondly obtaining an initial weight of an evaluation index by using an intuitionistic fuzzy entropy weight method, and fusing subjective preference information of a commander to solve an index weight optimization model, so that a weight result better meets the requirements of a battlefield; then, determining a dynamic decision matrix by adopting intuitionistic fuzzy cross entropy and relative closeness, processing the multi-moment information by adopting a normal distribution method, establishing a weighted dynamic decision matrix to present the air defense threat situation dynamically; and finally obtaining a threat degreesorting result of the incoming targets by using a TOPSIS method. The method can be applied to the dynamic air defense threat estimation of a naval vessel formation in an uncertain sea battlefield environment.

Description

technical field [0001] The invention belongs to the field of ship formation air defense decision-making, in particular to a ship formation dynamic air defense threat estimation method based on intuitionistic fuzzy TOPSIS. Background technique [0002] The air defense operations of ship formations in a high-tech and information-based environment need to fully integrate limited battlefield intelligence information and integrate the knowledge and experience of military experts to make effective and rapid decisions. How to accurately estimate the threat level of incoming targets is an important issue in the field of formation air defense decision-making. In the modern naval battlefield environment, the air attacks faced by ship formations have the characteristics of multi-weapon, multi-direction, and continuity, and the uncertain information is constantly increasing, which makes the commander's prediction and decision-making complicated and difficult. Threat estimation belongs ...
