Abstract:Manufacturing execution system (MES) is one of the important means to realize manufacturing informatization in manufacturing industry.In order to solve problems in different manufacturing industries and production enterprises,which leads to issues of large customization amount,long implementation cycle and high cost,a MES basic data modeling idea was put forward.Production factors such as personnel,equipment,materials,assets,tools,and processes were modeled.Through the establishment of the basic data model,the matching of the basic data from different manufacturing enterprises was realized.Then the implementation cycle of MES system is reduced,the implementation cost of MES system is reduced.
