Problems solved by technology

[0004] However, the above-mentioned traditional radar chart method has two shortcomings: one is that the index weight is not considered, and the other is that when the order of the indicators is changed, the drawn radar chart is not unique, which causes the uncertainty of the evaluation results. Carry out a comprehensive assessment, for the same indicator data (such as figure 1 shown), because of the different order of the indicators, different results appear in the drawing of the radar chart, such as figure 2 , image 3 shown

Abstract

The invention belongs to the technical field of ship power system comprehensive evaluation, and particularly relates to a ship power system comprehensive evaluation method based on an improved radar map. The method comprises the basic steps of data preprocessing, index weight determination, improved radar map drawing and feature vector extraction, the index weight is introduced into evaluation andanalysis of a radar map method, and the scientificity of evaluation is enhanced; Meanwhile, the problem that a traditional radar map is not unique is solved, the improved radar map method is visual in image and simple and clear in result, different objects can be compared transversely, longitudinal prices of the same object in different periods can be made, and good applicability is achieved.

Description

technical field [0001] The invention belongs to the technical field of comprehensive evaluation of ship power systems, in particular to a method for comprehensive evaluation of ship power systems based on improved radar charts. Background technique [0002] The comprehensive evaluation of ship power system plays an important role in ship launching, new ship delivery, task arrangement and other work. The pros and cons of the evaluation method have a direct impact on the comprehensive and systematic grasp of the technical status, performance and functions of the ship power system. Using the radar chart method to complete the above work is one of the commonly used methods. As a typical graphic evaluation method, the radar chart method is characterized by its intuitive image. It can not only conduct qualitative analysis by observing the graphic, but also perform quantitative analysis by extracting the features of the graphic. analyze. [0003] The main steps of using radar cha...
