It discusses the deciding principle of the charge by weight of road,and setting the freeway in Anhui province as example,it represents the deciding methods of charge from the division of the field of the weight of charge,the estimation of the ratio of charge and the model of charge by weight,puts forward the better fixed price program,to accelerate the further regulating of road cargo markets.

To solve these problems, a new AHP method is presented by combining the weight vector rang estimation analytic theory with traditional evaluation index rejecting method.

To make the solution be more flexible, an interval weight vector is obtained, which is achieved through linear programming method in this paper.

In this paper, a new method for the calculating weights in the uncertain interval judgment matrix is proposed, and the interval weight of alternatives are obtained by solving a program problem.

The weights of the four factors are evaluated with the method of interval weight and finally the paper uses the decision theory to determine which route should be chosen in multi-modal transportation.

After that,we study the correlations between extreme events using return interval,and compare the multifractal properties of the three types of time series.
