Based on the poor quality of present assemble sequence planning aimed at producing time and operating cost,stream of variation analysis method(SOVA) was applied to investigate sequence optimization of two dimensional multi-station assembly in order to improve the assemble quality of products.

An optimal tolerance synthesis method for multistation sheet metal assembly was presented,in which the manufacturing cost was selected as the objective function.

An optimal sensor design method was presented for the multistation sheet metal assembly processes.

Research on key technology of hydraulic manifold block assembly process simulation system

A theory and method of collaborative design of product assembly structures and assembly processes is ad- dressed.

According to the damages of oil-film bearing taper sleeve with elastic cohesion on hot continuous strip mill in some large steel company,3D boundary element method(BEM) for elastoplastic contact problems was used to qualitatively analyze the mechanical behaviors of sleeve and roll neck during the assembly process.

PERT graph is a good method to describe the produce process or assemble process in manufacture enterprise, and it can visually display the logic relation and produce schedule among all working procedure, but the PERT graph can’t show the resource’s effect to the produce process.
