Abstract
The computer simulation is a comprehensive nature very strong emerging technical science which develop the nearly 30 years, it involves to the system analysis, the control theory, the computational method and the computer technology. The system simulation is the use system model conducts the experimental study to the actual system the process. The manufacturing industry all holds the maximum proportion generally in the national economy, since the 20th century 70's, the global market competition has been day by day intense, the product consumption pattern to the multiplication, the personalized direction develops unceasingly, the product regeneration-period and the date of delivery all are reducing, some automated technology like CAD, CAM, CAPP, NC, FMS, MRPII and CIMS all obtained the fast development. The system simulation took one important method, usually may seep to them, and helps them to realize the integration, thus promoted some advanced technique of manufacture development. Introduced separately in the paper utilizes each system like automatic processing system in the simulation software, the physical distribution system as well as the robot.Also introduced the flexible manufacture system, as well as SL-MSM some main programs.
