Abstract

Abstract: The paper was aimed at overcoming the deficiencies of current risk assessment methods for hazmat road transportation. Typical characteristics of the risk in the transportation, including its uncertainty, randomness and dynamics,were examined. A novel risk assessment method for hazmat road transportation was worked out on the basis of both IAHP and SPA. A risk assessment model was built for this method and its calculation steps, being establishing a risk assessment index system according to the risk factors on hazmat road transportation, using IAHP to obtain the weights of assessment indexes, making a same-different-opposite analysis for the certainty-uncertainty system of hazmat road transportation, and studying the dynamic change of risk factors according to connection degree, were presented. The method was applied to assessment of risk in the recent hazmat road transportation of a certain enterprise taken as an example. The results show that the risk assessment grade is basically in accord with the reality, and that SPA can be used to assess the risk factors of hazmat road transportation and their change trends, which provides a solid foundation for the prevention and control of hazmat road transportation accidents.

Key words: interval analytic hierarchy process(IAHP), set pair analysis(SPA), set pair trend, hazardous materials, road transportation, risk assessment
