Based On Multi-agent Agile Intelligent Manufacturing Execution System

Globalization and information development is changing the manufacturing environment. As the bridge connecting the planning and managing layer and the facility control layer, the Manufacturing Execution System is the key factor to raise an enterprise's sensitivity. This dissertation focuses on the multi-agent based intelligent MES in agile manufacturing enterprise, its main theoretic issues and key technologies are multi- agent system (MAS), agent organization structure, agent communication and cooperation mechanism, the dynamic scheduling strategy based on the event-driven and period. In an attempt to tackle the most common resource conflict problem of I-MES, a conflict resolution model that is based on multi-agent cooperation is proposed. On the base of these, aiming at the disadvantage and drawbacks of the traditional Manufacturing Execution System in the agile environment, taking the flowing technology business such as tobacco business as the background, a Intelligent Manufacturing System that is open, integratable, dynamic, agile and operatable is established based on the multi-agent technologies. Meanwhile the general structure for manufacturing agent and the flow chart of the agent are described. The integration mechanism of the I-MES and ERP system and facility control system is discussed in this thesis, and realize the prototype of this system.
