Safety evaluation method of road transport facilities for hazardous chemicals based on improved ahp

Abstract

The invention discloses a method for evaluating the safety of road transport facilities for hazardous chemicals based on improved AHP. According to the characteristics of road transport of hazardous chemicals, road facilities, vehicle equipment and loading and unloading equipment are selected to determine the safety of road transport facilities for hazardous chemicals. risk factors; then combined with the safety risk factors to construct a safety risk evaluation index system for road transport facilities and equipment for hazardous chemicals, the safety risk evaluation index system is divided into four levels: A, B, C, and D, and evaluation factors are selected for each level; The improved AHP scaling method is used to construct the comparison matrix, and then the mathematical method is used to optimize the elements of each evaluation factor, which avoids the consistency test, and obtains the weight of each evaluation factor. Carry out a reasonable, objective and practical safety evaluation and analysis on the road transport facilities and equipment of hazardous chemicals.

Description

technical field [0001] The invention relates to a safety evaluation method for road transportation of hazardous chemicals, in particular to a safety evaluation method for road transportation facilities of hazardous chemicals based on improved AHP. Background technique [0002] With the continuous development of my country's chemical industry, there are more and more types and quantities of hazardous chemicals (hereinafter referred to as hazardous chemicals), which have been widely used in enterprise production and increasingly become an important pillar of economic development. According to the current statistical survey, there are more than 5,000 commonly used chemical raw materials, and the demand for hazardous chemicals in various industries is increasing at a rate of more than 10% every year. However, 95% of the hazardous chemicals need to be transported in different places. For railway transportation, waterway transportation, air transportation, pipeline transportation ...

Problems solved by technology

Among them, the patent with the publication number CN106682864A proposes a system and method for a safe and intelligent transport vehicle for dangerous chemicals, but it is mentioned in the article that the technology is not systematically managed on roads and vehicles, and it does not explain how to monitor and manage transport vehicles. To improve the safety of vehicles during transportation, if ITS (Intelligent Transportation System) is introduced into the road facilities and equipment, with the help of computer science and technology and the application of GPS, managers can monitor the whereabouts of vehicles on the road in real time, which can be effective Make full use of existing traffic facilities, reduce road traffic load, plan the most reasonable transportation routes in advance, improve vehicle traffic efficiency, realize intelligent transportation, and ensure vehicle traffic safety

[0004] However, the types of hidden danger factors in road transport of hazardous chemicals are extensive and dispersed, and the standards and attributes of each evaluation factor are different, but there is a certain connection and hierarchy among them. Safety evaluation analysis will lead to fuzzy evaluation results, not hierarchical and not very practical

At present, there is no comprehensive evaluation and analysis of risk hazard factors of hazardous chemicals with many categories and strong dispersion. Therefore, it is necessary to establish a systematic and hierarchical safety system for road transportation facilities and equipment of hazardous chemicals Evaluation comprehensive system, and then carry out a reasonable, objective and practical safety evaluation analysis on the road transportation facilities and equipment of hazardous chemicals
