The manufacturing scheduling program has to optimize the structure of the production , lower the rejectscheaply and enhance the durability and after severce in order to make the product reliable. 2) Product cost: including the utilization ratio of equipment, cost of the raw materials and wastes discharge.
The manufacturing scheduling program should apply new and high technogy to enhance utilization ratio of equipment, save the product raw materials and reduce the wastes discharge. 3) Product safety: including equipment loading, equipment block and shortage of material.
By the figure, we can see that the weights of the factors of the manufacturing scheduling program have this relation: equipment loading> shortage of the material>equipment block>customer satisfaction>equipment efficiency>product quality>cost of raw material>wastage discharge.

Introduction Along with the development of science and technology, especially the extension of electromagnetic technology application, more and more friction pairs of electrical equipments and appliances have been used under the electromagnetic condition, and most of the materials used are ferri-magnetic and therefore the study on the influential factors and regularity of friction and wear characteristics of ferri-magnetic friction pairs under a magnetic field condition and the establishment of theoretical basis and guideline for concurrent tribology have become critical topics for mechanical designs.

This can be a challenging task in the case of composite materials and structures, such as masonry, when using conventional measurements.
However, the excessive loading and deterioration of the original materials evoke a concern about their durability and the preservation of old monuments became an issue.
Later it has been successfully used on various materials, e.g. to study deformation of textiles [4], fatigue of polymer materials [5] or cracking patterns in masonry walls [6].
Such a full-field approach allows an efficient observation of localization phenomena, such as necking in metals or crack initiation in brittle materials.
