Abstract
To comprehensively understand the research progress of the fleet scheduling for hazardous materials, the study has summarized the corresponding research results from three aspects (a) hazardous materials transportation risk, (b) route optimization, and (c) fleet scheduling, and then pointed out potential problems from six aspects: (a) the coupling risk of the transport fleet; (b) the screening of time and space for the transport of hazardous materials; (c) the scheduling optimization for transport fleets; (d) taking insufficient account of transport risks fairness; (e) insufficient robustness of scheduling schemes; and (f) lacking of research results on fleet scheduling of transport in the context of antiterrorism. After that, by considering the existing shortcomings of the current research, five research directions are presented that should be further explored in the future. Subsequently, both rough set and association rule theory is applied to explore the cause chain of transportation accidents for hazardous materials, and analyze the mechanism of transport accident for hazardous materials. Next, the Bayesian network is presented to predict the accident rate of hazardous materials transportation under different temporal and spatial conditions, and the dynamic rolling scheduling method of hazardous materials transport fleet is constructed under normal and antiterrorism background.
Highlights
Hazardous materials are referred to those substances and articles with explosive, in ammable, toxic, infectious, corrosive, and other dangerous characteristics that are liable to cause human casualties, property damage, or environmental pollution in the course of production, management, transportation, storage, use, and disposal, which is required special protection
To comprehensively understand the research progress of the eet scheduling for hazardous materials, the study has summarized the corresponding research results from three aspects (a) hazardous materials transportation risk, (b) route optimization, and (c) eet scheduling, and pointed out potential problems from six aspects: (a) the coupling risk of the transport eet; (b) the screening of time and space for the transport of hazardous materials; (c) the scheduling optimization for transport eets; (d) taking insu cient account of transport risks fairness; (e) insu cient robustness of scheduling schemes; and (f) lacking of research results on eet scheduling of transport in the context of antiterrorism
It can be seen that many scholars have carried out a large number of studies on transport accidents and transport risks of hazardous materials, and established a lot of risk measurement models, especially the three risk axioms proposed by Erkut and Verter to evaluate the correctness of the transport risk model, which provides an important basis for our research on transport risks of hazardous materials
Summary
Hazardous materials are referred to those substances and articles with explosive, in ammable, toxic, infectious, corrosive, and other dangerous characteristics that are liable to cause human casualties, property damage, or environmental pollution in the course of production, management, transportation, storage, use, and disposal, which is required special protection. Over one billion tons of hazardous materials are transported by road in China every year. Transport accidents of hazardous materials have occurred frequently in China, which causes harm to vehicles and humans, and produces serious damage and pollution to the environment around the route. Hazardous materials transportation is an important part of the life cycle, which o en goes through town or areas of the crowd, and in the event of an accident, heavy casualties may occur, leading to pollution of the environment for a long time and huge economic losses. E results are of great significance to prevent the occurrence of hazardous material transportation accidents and ensure the security of people’s lives and properties The robust dispatching models, solving algorithm, and dynamic rolling dispatching system of transport at fleet, are constructed to achieve safe, economic, and efficient dispatching of transport fleet. e results are of great significance to prevent the occurrence of hazardous material transportation accidents and ensure the security of people’s lives and properties
