A new idea to guide software quality evaluation was proposed,which used minimum confidence as the membership rule,and used evaluation analysis,based on the quantified weight and satisfaction,as the analysis approach.

According to the characteristics of color imagine matching,sequential similarity detection algorithm(SSDA) was inproved based on color weight coefficient.

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.
