Get the best index weight coefficients by minimizing the difference between real evaluating value and ideal evaluating value and maximizing the entropy of weights of each coefficient.

Used the Analytic Hierarchy Process,which has established the weight value of the urban evaluation index weight system of living environment,and do the quantized treatment to the comprehensive living environment of city.

AHP algorithm of the index weight of the result estimate of the research institutions in the local colleges and universities;

A study of scaling method to obtain index weight by analytic hierarchy process;

A simple method of determining the index weight of maturity evaluation based on order relation

AHP confirming weight of index by matter element analysis;

To overcome the shortcomings of the methods to subjectively or objectively determine the weight of indexes, the group eigenvalue method combining with the variation coefficient m.

It is effect that the weight of index in performance evaluation of employees is calculated with AHP.

This method solves the problems in determining weigh, such as concentrating different experts′ ideas, constructing evaluation matrix reasonably and checking up its coherence.
