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