Erp Implementation Study Of Engineering Modeling And Simulation

The development and application of the information technology bring the conflict between the new unprecedented way of thought and work and the traditional mode of management for the enterprise. Although numerous enterprises long for informational management, they have all kinds of perplexity and fear. Before the practice of the ERP project, the businesses usually need to consider of three problems that are the consultation, the choice of products and the evaluation of the system value.However, the putting of ERP system into practice is filled with the challenge and risk, and many companies input a huge sum of funds on ERP project, however, gain little efficiency. As the scale and complexity of the ERP system become more and more great, the requirement for modeling of system is continuously increased.The paper systematically introduced the application, process of development and primary modules of ERP. Aiming at the inscrutable difficulty met in the process of the putting of ERP into practice, it makes model and analysis by using the modeling technology of two-dimension graph, and resolve the collide of the resources induced by concurrent affairs of the system during the course of modeling for the orderly running of the system. At the same time, it adopts the method of the matrix analysis in order to control the change of resources flow of the system. The thesis gives the example about the subsystem of manufacture management of the ERP to introduce the modeling technology of Petri net. It brings forward the method of the macro transition, which can control the system macrocosmically and feed back every detail of the manufacture process microcosmically. Finally, the paper also introduces the application and development of the simulation technique detailedly, and simulates the order manage with GPSS, a simulation language.
