Problems solved by technology

However, if the traditional TOPSIS (ranking method approaching the ideal solution) in the field of multi-attribute decision-making is directly used for evaluation, it is only applicable to the relative ranking of multiple schemes in the same evaluation, and the evaluation results cannot be reused

Embodiment Construction

[0064] Taking the index system of the electromagnetic compatibility performance of the vehicle communication system as an example, the implementation mode of the present invention is analyzed, and its flow is as follows figure 1 shown.

[0065] Step 101: Establish an index system, the EMC performance index system of the established vehicle communication system is as follows: figure 2 shown.

[0066] In this model, the target layer and the index layer present a hierarchical tree structure, and each index in the index layer is relatively independent by category, including performance types that represent the electromagnetic compatibility of platform carriers such as layout performance, interconnection systems, and grounding systems; power systems, The performance type of the electromagnetic compatibility of the uploading mission system such as equipment characteristics; and the data of the sub-indicator layer presents a classified network correlation feature, that is, each typ...

Abstract

The invention belongs to the field of comprehensive electromagnetic compatibility evaluation, and particularly relates to a comprehensive electromagnetic compatibility evaluation method for a complicated electronic information system. The method is characterized by at least comprising the following steps of: 101, establishing an electromagnetic compatibility index system of a vehicle-mounted communication system; 102, acquiring original data of an index layer in the index system; 103, quantifying the original data of the index in the index layer; 104, acquiring an initial evaluation vector according to the quantified data corresponding to the indexes; 105, calculating a target weight vector for the index system according to an analytic network process (ANP) method; 106, performing performance concentration according to an improved TOPSIS method; and 107, analyzing an evaluation result. Positive and negative reference points are determined by a generalized reference point search method based on historical database sample statistics and replace ideal positive and negative points determined in a scheme to be evaluated by the conventional TOPSIS method; and furthermore, the close degree is calculated by a weighted euclidean distance, so that the problem that the evaluation result is reused is solved.

Description

technical field [0001] The invention belongs to the field of electromagnetic compatibility comprehensive performance evaluation, in particular to a complex electronic information system electromagnetic compatibility comprehensive evaluation method. Background technique [0002] EMC evaluation of the system includes subjective evaluation using expert scoring methods, test verification, paired or group evaluation of equipment in the system, and interference prediction and evaluation of key sensitive equipment in the system. The main idea is to evaluate the final performance of the system. The predictive analysis or test of the system cannot reflect the impact of various design elements in the system (such as layout, interconnection, grounding and other integrated design factors) on the final performance. The evaluation results obtained by this type of method are not conducive to guiding the system electromagnetic compatibility design or production level improvement. [0003] ...
