With the increasing demand from the home furnishing market for rapid response to customer requirements,improvement of product quality and shortening delivery time,the panel customized furniture enterprises took the lead in introducing the advanced enterprise management system,while bringing about the problem of information fault between the management and the manufacturing workshop. In order to explore this advanced enterprise management system of the panel customized furniture enterprises,the solution of manufacturing execution system(MES) was put forward. Based on the unique feature of the panel customized furniture enterprises,the system architecture of the MES was proposed distinguishing from the other industries. Through the analysis of the production problems,including difficulty of order scheduling,transferring important production information in traditional way,lack of production planning and scheduling,and poor feedback of production status,and the characteristics of the MES for panel customized furniture enterprises which included the differentiation of products and components,production drived by digitalization and production information integration,the functional modules of the MES for panel customized furniture enterprises were suggested. Its detailed diagram was drawn,from which,it can be found five functions of the MES for panel customized furniture enterprises including the basic data management,production data collection,production planning management,material management and production process management. The implementation of the MES for panel customized furniture enterprises was discussed from three aspects of system structure,functional hierarchy model and hardware architecture. Based on the three-layer structure of ERP/MES/PCS,the system structure of the MES for panel customized furniture enterprises was designed and the characteristics of information transmission between three layers were expounded according to the MES structure drawing for panel customized furniture enterprises.Furthermore,the functional hierarchy model of the MES for panel customized furniture enterprises was presented,which was divided into data acquisition layer,basic data layer,data access layer,business function layer,and presentation layer. In the functional hierarchy model diagram of the MES,the relationship and characteristics of information transfer between the five layers were analyzed. Meanwhile,on the basis of data exchange methods between each working procedure and system,the hardware architecture of the MES for panel customized furniture enterprises was structured in order to realize data acquisition and transmission of the whole production process,resulting in hardware devices connection through workshop bus,personal digital assistant(PDA) transmitting data through wireless network,local users viewing data through Client/Server,and remote users completing the corresponding operation through the Browser/Server in the hardware architecture diagram. With the help of the timely feedback of the production data by the MES,the transparent management of the workshop was realized,and the gap between the management and the manufacturing workshop was filled up. Through the implementation of the MES,the production efficiency and competitiveness of panel customized furniture enterprises would be improved.
