Through establishing hierarchical framework model,and determining the coefficient of difficulty and weight vector,integrated scores of different water supply modes were derived to select the economical and reasonable water supply mode.

There are many factors affect the load,and it is difficult to choose the weight vector,which lead to the worse veracity.

In this paper, computing method of solving weight vector of judgment matrix by means of the least squares principle and the Lagrange s multiplier method is derived.

The peak energy amounts of the different frequencies of the loosing signals of turbine are utilized as training samples to input the LVQ network, and then the network outputs the scale vectors after training.

The peak energy amounts of the different frequencies of the loosing signals of turbine are utilized as training samples to input the LVQ network,and then the network outputs the scale vectors after training.

The ways to get weighting vector are also put forward,with the Maths model of fuzzy evaluation of optimized layout of city freight transport hubs being established.

By defining digital judgement matrix of judging matrix between departure matrix and relative interval number,a new ealculating method of judging matrix weighting vector with inter- val number under condition of group decision is given.

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.
