According to image texture characteristic,a kind of image feature statistic was defined,by using feature weight assignment operators designed here,the proposed method.

By means of fuzzy identification technique, the author demonstrates the application of a method of optimized distribution on the weighed distribution of multiple paramaters selected from geological, geochemical parameters of the composite evaluation of east Junger region predicts east Junger gold-ore advantageous regio

Secondary decision making of weight distribution in environmentalsystem;

Application of "three step method" in defining weight distribution of evaluation indexes;

Therefore, random and error of weight distribution in the assessment of leather subjective .

This paper presents three algorithms of weight assignment which is used to solve the problem of the destination selection.

A case study indicates that,at a certain extent,subjectivity of proportion problem is reduced,and the factors proportion is optimized after eliminating some experts results by using the euclidean distance.
