Objective: Establishing a subjective and objective method to conform the weighted coefficient in multicriteria optimization of the extraction technology about Chinese traditional compound drugs.

During the past years, most of the researchers have been using the unweighted coefficients, even now no proper weighted coefficients of genetic distance are available.

In the evaluation of performance,there are many ways of deciding the weighted coefficient The way of Analytic Hierarchy Process (AHP) is simple,available and higher accurate.

Evidence combination method based on the weight coefficients and the confliction probability distribution;

Definition of weight coefficient in sport evaluation;

Study on different residual and weight coefficient in model updating of structure;

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.

It is very important for evaluating traps to study out the key geologiccal factor's weighting coefficient .

This article used Analytic Hierarchy Process to conform the weighting coefficient of all the indicators in the analysis system.

The number of levels,evaluation levels,weighting coefficient and evaluation matrix shou.
