Risk analysis of hazardous materials transportation: evaluating uncertainty by means of fuzzy logic

摘要

This paper provides an application of fuzzy logic to the risk assessment other transport of hazardous materials by road and pipeline in order to evaluate the uncertainties affecting both individual and societal risk estimates. In evaluating uncertainty by fuzzy logic, the uncertain input parameters are described by fuzzy numbers and calculations are performed using fuzzy arithmetic; the outputs will also be fuzzy numbers. This work is an attempt to justify some of the questions the use of fuzzy logic in the field of risk analysis stimulates.
