As an advanced manufacturing mode, networked manufacturing can achieve not only information sharing and integration within enterprise but also collaboration of different enterprises with the aid of advanced manufacturing technology, networked technology and related technologies. As an important part of CIMS, Manufacturing Executing System (MES) is the production management system on the shop floor, which fills the communication gap between the manufacturing planning system (e.g. MRPII/ERP) and the control system. It aims to integrate the production process in terms of labors, materials, equipments and work-in-progresses so as to achieve the effective production and control on the shop floor. However, most existent MES systems lack the ability to integrate the manufacturing resources and communicate with other information systems within the enterprise or with other enterprises.This thesis presents a networked MES solution, where a manufacturing resource integration execution system is developed to support networked manufacturing for virtual manufacturing organizations. The background, objective and significance of the project are introduced. The essence, functions and research on "Regional Networked Manufacturing" are summarized. The development of networked manufacturing MES technology is discussed. The disadvantages of the traditional MES in the networked manufacturing environment are put forward. Meanwhile, the necessity and feasibility of the manufacturing resource integration modeling and information issuance are pointed out. According to the investigation in Chengdu Wangpai Vehicle Company, the network hierarchy for the shop floor resource modeling is proposed. The multi-agent-based static manufacturing resource model and the UML-based dynamic model are both developed. Lastly, the integration architecture of the manufacturing resource modeling in the networked shop floor environment is established and the solution of the integrated and networked MES is presented. Base on the achievement above, a prototype of the networked MES based on DOTNET is described. The requirement analysis, function description and database design are discussed in detail. This system is put into practical use, and some examples are given. Finally, the conclusions are drawn and the further research directions of MES in a networked manufacturing environment are pointed out.
