COMPUTER MODELLING FOR RISK ASSESSMENT OF TRANSPORTATION USING METHODS OF FUZZY SET THEORY

Computer software for risk assessment of transponation of imponant freight has been developed. It incorporates models of transpon accidents, including terrorist attacks. These models use, among the others, input data of canographic character. ~graphical information system technology and electronic maps of an area are involved as an instrument for handling this kind of data. Fuzzy set theory methods as well as standard methods of probability theory have been used for quantitative risk assessment. Fuzzy algebraic operations and their computer realisation are discussed. One preliminary example of risk assessment is described.
