Research On Application And Simulation Of Production Capacity In Discrete Manufacturing Enterprises

The rapid development of manufacturing technologys bring about not only challenges but also opportunities to the discrete manufacturing enterprises. The advanced manufacturing technology and management methods which are used to improve the production capacity, the production efficiency and the capacity to respond the market swiftly are becoming the important means to enhance the competition force of enterprises. Competition is becoming more and more drastically in the opened market environment, which makes the promotion of production system and the further increase of production capacity are turning into urgent affairs.This paper bases on the correlative theory study about production capacity, the simulation and modeling research aiming at the production system in the discrete manufacturing enterprise through computer technology. Moreover, this theory is used by IE and BPR, which have laid the scientific foundations of the decision-making of enterprises. The research of this thesis focuses on the following aspects mainly:1. The new circumstances that the discrete manufacturing enterprise is confronted with are analyzed; the function and configuration of production system is expounded; the research actuality and contents about production system capacity in the discrete manufacturing enterprise are summarized; the main research contents in this paper are developed.2. The calculating and analytical methods about production system capacity are studied systemically, a model to calculate rough-cut capacity instantly in "excel" table style is designed, the means to analyze production capacity in different production mode are brought forth, and the balance tactics of production capacity versus load are put forward.3. The application characteristics used in production system about the methods of Computer simulation and CRP in the MRPII/ERP are analyzed and compared; the advantages of Computer simulation method are pointed out; and the simulation researches aiming at production system capacity are implemented by Ithink simulation software.4. A simulation model is founded under the analysis of production system capacity in the production system background of a firm; the change instances of yield, output rate and WIP(work in process) in the production system are simulated by the action of procurement cycle, machining time, setup time and so on. 5. The change instances of production capacity in the assembly stage are simulated , and rational employees are obtained.Finally, all of the research work is summarized , and further conceive about the research of production system are brought forward.
