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.

To solve synchronization problem in assignment of machines to operations and the scheduling of operations on the assigned machines in Flexible Job shop Scheduling Problem(FJSP) with multi-objective,a hybrid genetic algorithm combining random weigh method with niche technology was proposed.

On the basis of many methods, the paper provides a new method method of changing importance coefficient, which is widely useful and accurate The method can measure the speed of science and technology progress and its contribution rate correctl

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.
