Transdermal absorption experimentation of paracetamol was detected on the device of penetrating skins of rabbit in vitro and penetrating rates,steady fluxs,lag time and enhancement ratio were calculated to evaluate promoting effects of transdermal enhancers with fuzzy matter-element model based on variation coefficient weight.

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;
