The following is the assumption for the process industry production scheduling model:1) Each device can only carry out a certain process step of one production in each time, and the next step can be started until the previous process step is completed;2)The process time for each process step is certain,and the equipment preparation time is included in the process time;3)There is no binding of priority between the process steps of different products; 4)All of the process batches of materials are certain, and the material balance problems are not considered;5)There are no other resource constraints except of equipments.6) The materiel shift time between devices is ignored;7) The unlimited intermediate store policy is used to storage materials.

Improving the microwave absorbing property of fiber reinforced /resin by surface modification of fiber through ion implantation Yun-fei Bi1, a , Tao ye 1,b, Liu pei-ying 1,c 1 College of Materials Science & Technology, Beijing University of Aeronautics and Astronautics, Beijing 100083, China a beiyf2003@163.com, bttaoye@163.com, cLiupy@buaa.edu.cn Key words: Ion impregnation, fiber reinforced composite, microwave absorbing , Abstract.
Introduction Fiber reinforced /resin composites are the most commonly used structural materials for aero flight.
If ferromagnetic materials were implantation into samples, the property of wave-absorbing would be improved because of additive ferromagnetic ullage etc[5，6].

Equivalent strain distribution Due to the large size and complicated structure of research object, materials can only fill the die cavity under stronger forces.
In the filling stage when the die core shoulder touches the blank materials, blank materials are driven by external forces to fill the die cavity gradually, reducing the free surface and increasing metal flow resistance accordingly.
In the final stage, the workpiece flange and upper and bottom corners are all filled with blank materials.

The reason may be due to that no chemical reactions between different compositions including tar, clay and pitch occurred at this low temperature; in other word, no harmful materials were formed.
This work is helpful for understanding the possible property transition of the tap-hole clay in the tap hole and also provides research method for other composite materials.
