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;

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.

Method for determining weight coefficients of sluice health comprehensive diagnosis;

Objective The methods of weight and standardization were studied in order to evaluate comprehensively the reproductive health status and care level of an area in our country.

With application of Analytical Hierarchy Process (AHP) to supplier risk assessment through creating hierarchy structural model, constituting judge matrix, sorting on criteria hierarchy and validating consistency on conclusion, the weight of each risk factor will be calculated and determined respectively.

It is important to choose the weight factor between track alignment irregularity and level irregularity in the management of track complex irregularities because they affect train riding stability.

Based on this method, a month average weight factor equation in choosing standard year (or season) has been derived.

To avoid the excessive subjectivity influenced by the conventional determination methods of weight factor,the rough set was introduced to the solution of the weight factor in the extenics evaluation.
