Based on the analyses of current researches of optimization methods for fixture layout and clamping forces,a new method using Genetic Algorithm and finite element method was presented.

Fixture layout and clamping forces can influence the value and distributing of machining deformation.

Based on finite element method, this thesis explores a feasible method that can optimize fixture layout and clamping forces simultaneously.

A compretensive evaluation of the layout scheme of railway logistic center;

Basing on the module demarcating of respective manufacturing locality of the product line of double-entry stuff spreading system, with the mode by combining basic module, a group of schemes combining with product practicality are advanced; then, according to the technical character of the stuff spreading system, three elementary layout schemes are designed as the concretly advisable schemes grou.

Considering the unconventional buoyancy-lift analysis and structural design,the layout scheme of the WBAC was given;the overall design was finished;the test aerocraft was made and the test flight was successful.

Based on the utility analysis in the economics,by searching the key path between a traffic mode and another transfer mode in the intermodal transfer points,a utility cost model is put forward to evaluate and optimize the facilities layout alternatives of the urban intermodal passenger transfer points.
