Safety evaluation method for hazardous chemical road transportation facility based on improved AHP

Abstract

The invention discloses a safety evaluation method for a hazardous chemical road transportation facility based on improved AHP, and the method comprises the steps: selecting road facilities, vehicle equipment and loading and unloading equipment according to the characteristics of hazardous chemical road transportation, and determining the road facilities, the vehicle equipment and the loading andunloading equipment as safety risk factors of the hazardous chemical road transportation facility equipment; then, constructing a safety risk evaluation index system of the hazardous chemical road transportation facility equipment in combination with safety risk factors, dividing the safety risk evaluation index system into four levels A, B, C and D, and selecting evaluation factors for each level; adopting an improved AHP scaling method to construct a comparison matrix, then adopting a mathematical method to perform element optimization on each evaluation factor, so that consistency check isavoided, the weight of each evaluation factor is obtained, and finally calculation is performed by integrating the weights of all the evaluation factors. Reasonable, objective and high-practicabilitysafety evaluation analysis can be carried out on the aspects of hazardous chemical road transportation facilities and equipment.

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 have increasingly become an important pillar of economic development. According to the current statistical survey, there are more than 5,000 kinds of chemical raw materials commonly used, and the demand for hazardous chemicals in various industries is increasing at a rate of more than 10% every year. However, 95% of hazardous chemicals need to be transported to other places. For railway transportation, waterway transportation, air transportation, pipeline transport...

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
