Modeling and simulation optimization of purchasing process based on Petri net

Abstract

Taking the purchasing process of a domestic large-scale manufacturing enterprise as research object,the models of purchasing process in the original environment and the optimized environment were built using the Petri net technology,and the performance under both conditions were quantitatively analyzed and then the strong and weak points in the original and the optimized processes were discovered by the simulation using the software ExSpect.The results show that the optimization of the original process by using the information technology and the reasonable supplier selection methods speed up the transferring and processing of the business information and shorten the purchasing period.
