Evaluation method for maritime traffic safety monitoring capability based on entropy weight method and variable fuzzy method

Abstract

The invention discloses an evaluation method for a maritime traffic safety monitoring capability based on an entropy weight method and a variable fuzzy method. The method comprises the following stepsthat S1) evaluation factors of the maritime traffic safety monitoring capability are determined, and an evaluation index system for the maritime traffic safety monitoring capability is constructed from the factors of labor, apparatus and management; S2) index weights are calculated according to the entropy weight method; and S3) a lever characteristic value of the maritime traffic safety monitoring capability is determined according to the variable fuzzy method. According to the evaluation method, the evaluation factors of the maritime traffic safety monitoring capability are formed to evaluate the capability, and monitoring resources are distributed reasonably based on a monitoring capability evaluation result.

Description

technical field [0001] The invention relates to the field of water traffic safety risk assessment, in particular to a water traffic safety supervision capability evaluation method based on an entropy weight method and a variable fuzzy method. Background technique [0002] According to the principle of risk management, the level of risk requires corresponding risk elimination measures, which means that the supervision of water traffic safety requires that the supervision capacity must match the risk level; at the same time, in order to realize the rational use of supervision resources, it is also necessary to effectively manage the supervision capacity. Evaluate. [0003] At present, the existing technical solution closest to the present invention in the field of regulatory capacity assessment is the entropy weight method combined with the TOPSIS method. The disadvantage of this solution is that it is suitable for dealing with those factors with unclear boundaries and difficu...

[0003] At present, the existing technical solution closest to the present invention in the field of regulatory capacity assessment is the entropy weight method combined with the TOPSIS method. The disadvantage of this solution is that it is suitable for dealing with those factors with unclear boundaries and difficult quantification, which affects the accuracy of the evaluation results.
