The optimum seeking method is the shortest way of leading to the plans of production and scientific research.

Its processes are that first,it is to establish an evaluation model for the oil-gas field development projects,in the second place,the optimal normal value is calculated out by means of the optimum seeking method in order to determine the optimal objects,at last,according to its order.

In this paper,basing on the maneuvering mathematical model,we consider the influence of environments,then choose the opti-mum rudder s shifting time by the use of optimum seeking method.

Simulation Research of Parameter Rectifying in Complex Control Systems with Optimization;

Using stone powders and residues from stone processing factory as raw materials,applying the optimization to experiment in the fundamental layer of floor brick,a new formula is obtained.

(sluice gate CAD)Furthermore,the paper also uses optimization to calculate the relation between discharge and water depth.

Optimization method, optimized mathematical model, process of method optimization, and some examples of mathematical model used in computer simulation are presented in this paper, and the optimization technique for parameters of making model by optimization method is introduced.

This paper introduced the optimized method of selection of cutting-tool angle.
