Route selection for dangerous goods based on D numbers

Route selection for dangerous goods transportation is a hot issue which involved in much uncertainty, fuzziness and incompleteness. In this paper, D numbers theory is used in the route selection for dangerous goods to deal with these information, both complete and incomplete, qualitative and quantitative. The three main criteria “transportation cost”, “risk during the transportation” and “emergency response ability” are considered to evaluate the routes and dijkstra algorithm is used to find out the optional way. An illustrative example is presented to demonstrate the effectiveness of the proposed method.
