System modeling and simulation of order processing based on extend technique

As a crucial and critical aspect of the third parties operation, order processing determinates the performance of the service. This situation sheds a light to the importance of order processing. After analyzing the processing flow, this paper proffer a discrete system model and imitate this model via deploying Extend simulation software, on the basis of which several defined approaches are figured out. By the same token, compare the baseline case with polished programs to incarnate the advantages of the later ones.
