In this paper

the brittleness of the complex system is introduced to the study of the traffic system.According to the hierarchy structures of complex systems

we analyze the brittleness of the traffic system with the Fuzzy Analytic Hierarchy Process(FAHP).In order to describe the relative importance between any two elements exactly

we modify the FAHP method.A reciprocal two-dimensional comparison matrix of objective sets is established with nine scales

and a combined method of both the square-root and power ...
