Based on the analyses of current characteristics and treatments of employee s violations of civil aviation corporation,punishment criterion calculation model based on exponential weight was put forward.

In this paper,we discovered the theoretical connection between the validity of FCM algorithm as clustering algorithm and clustering validity,and pointed out that the weighting exponent m is not the optimal if it mak.

Through the case study,three calculation methods of the index weight including AHP method,entropy weight method,entropy-AHP method,and two comprehensive evaluation models of the sustainable forest management including the linear weighted sum model,the weighted index model were compared and analyzed.

The algorithm core is to apply the group volume system to the matrix theory method to establish the mathematical model in which the multi-objectives optimize,using the weight coefficient method to transform the multi-objectives to the simple target.

Using the comprehensive evaluating method of multi-weighted index, this paper quantitatively analyzes the relationship among physical exercise, body upgrowth, studying results of first grade students of a key senior high school in one s own province.
