Modeling and Performance Analysis of Manufacturing Execution SystemBased on Petri Net

摘要

The current Manufacturing Execution System (MES) has many weaknesses, such as poor generality, weak reconfigurabilityand difficult performance analysis. In order to solve these problems, a functional decomposition diagramwas designed based on the functional requirements of MES, and a general petri net model was also established. The complexityand junction features of the model were analyzed based on Petri nets, and the network core layer and system reliabilitywere gotten after the model was transformed to the undirected network diagram. Finally, the best system schemefor different selections was given based on the analysis of reliability.
