Purchase cost of EMS includes material costs, ordering costs, maintenance costs and shortage costs.
Limitations on purchase costs control of EMS corporations. 1st : ineffective purchase cost control: in the BOM of EMS, more than 80 percent of materials are appointed by OEM. 2nd : External market is unpredictable. 3rd orders uncertainties.

Study of Magnetics Performance of Inset Permanent Magnet Synchronous Machine (Inset - PMSM) using Finite Element Method Jeeng-Min Linga, Tajuddin Nurb Department of Electrical Engineering, Southern Taiwan University of Science and Technology, Taiwan ajmling@mail.stust.edu.tw, bnasir_tan76@yahoo.com Keywords: Permanent Magnet, Finite Element Method Magnetics, Air Magnetic Flux Density, Inset Mounted Magnet Machine.
In this study, we use NdFeB material to build permanent magnet rotor and M-19 steel material for stator and rotor core.
To predict the PMSM magnetic field pattern and characteristics is difficult because of irregular geometry and non-linear magnetic materials in the machine.
It is popular in the field of science, engineering and education.

For the CFRP is twined around the column, it can limit the lateral deformation of internal materials.
From the figure 3(2) to (5), we can conclude that all the materials are yield in the pressure area.
In elastic-plastic stage, most of the materials are yield and the bearing capacity of the column increase slowly.
The bearing capacity will rise to the peak when most of the materials reach to be yield.

(3) It stores both paper-type materials and electronic digital resources
Some like reading book-type materials others prefer reading on Internet.
The input of human labor, finance and materials to the library should be reasonable and smooth to achieve continual improvement and timely adjustment.
The drawback is scattered paper-type materials and dispersed working places of librarians.
