This algorithm builds a nonlinear relationship between the step size and the weighting coefficient,which makes the step size decrease with the change of weighting coefficients until the step size reduces to zero.

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.

In allusion to the existing difference of selecting living consumption water quantity standard,this paper calculates the day and hour variety coefficient through testing calculation according to the population and construction age,and put forwards the living consumption water quantity standard in Shengyang City and provides the science reference for the water supply plan and design.

Constituting the quota system,the paper gives the degree of correspondence of this capability by variety coefficient of statistics, and proceeds with the simulative study.

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.
