Water hazardous chemical accident emergency aid decision-making method, terminal equipment and storage medium

Abstract

The invention relates to a water hazardous chemical accident emergency aid decision-making method, terminal equipment and a storage medium. The method comprises the following steps: S1, constructing a case database; S2, extracting an attribute value of each characteristic parameter corresponding to cases according to the characteristic parameters of the set cases; S3, calculating the weight of each characteristic parameter based on a rough set dependency enhancement method; S4, classifying the cases in the case database, and calculating the class to which the target case belongs through a Bayesian model; and S5, according to the class to which the target case belongs, extracting all cases under the class in the case database, and according to the attribute value and the weight of each feature parameter corresponding to the case, calculating the global similarity between the target case and each extracted case, taking the case corresponding to the maximum global similarity as a similar case of the target case, and determining an emergency aid decision-making scheme of the target case according to the similar cases. According to the method, the problems of high difficulty, unscientific scheme and the like of a current decision scheme after a water hazardous chemical accident occurs are solved.

Description

technical field [0001] The invention relates to the field of emergency auxiliary decision-making for accidents, in particular to an emergency auxiliary decision-making method for hazardous chemical accidents on water, a terminal device and a storage medium. Background technique [0002] Due to the economy, large volume and convenience of waterway transportation, the number of dangerous chemicals transported by waterway is increasing. However, under the influence of the particularity of hazardous chemicals and the complexity and sensitivity of the transportation environment, there are huge risks in the transportation of hazardous chemicals on water, and transportation safety has attracted much attention. According to statistics, from the mid-1960s to the 2010s, more than 3,200 accidents of various types of dangerous goods occurred in the past 50 years, among which the proportion of accidents involving the transportation of dangerous chemicals by sea was as high as 41%. The s...

AI Technical Summary

Problems solved by technology

Existing research on accident decision-making based on case-based reasoning has problems such as incomplete case database data, unreasonable index selection, and low retrieval efficiency.

Moreover, most case retrieval methods have fuzzy information without too much consideration of index attributes, and the determination of weights mostly relies on human subjective judgments
