Intelligent manufacturingAn overview Intelligent manufacturing deep in artificial intelligence research. Generally think that intelligence is the sum of knowledge and intelligence, the former is the basis of intelligence, the latter is the ability to acquire and apply knowledge to solve. Intelligent manufacturing should contain intelligent manufacturing technology and intelligent manufacturing system. The intelligence technique of manufacture is refers using the computer simulation marks intelligent activities such as experts analysis, judgment, inference, idea and decision-making and so on, and fuses organically these intelligent activity and the intelligent machine, applies its penetration in entire manufacture enterprises each subsystem (e.g. management decision-making, purchase, product design, productive plan, manufacture, assembly, quality assurance and market sale and so on).Realizes the entire manufacture enterprise to manage the operation highly flexibility and integration, thus substitutes or extends in the manufacture environment experts partial mental labor, and carries on the collection, the memory, the consummation, sharing, the inheritance and the development of the manufacturing industry experts intelligent information, enhances the production efficiency enormously and the advanced technique of manufacture. The intelligent manufacture system is refers based on IMT (intelligent manufacturing technology), by the computer synthesis application artificial intelligence technology (e.g. artificial neural networks, genetic algorithm and so on), the intelligence manufacture machine, the agent technology, the parallel projects, the life sciences and the systems engineering theory and the method, in the international standardization and interchangeable foundation, causes the entire enterprise to make each subsystem to intellectualize separately, and causes the manufacture system to form by the network integrates, the high automated one king of manufacture system.Intelligent manufacturing system can not only in practice constantly enrich the knowledge base, have the function of self-learning, and collecting and understanding of environmental information and its information, analysis and judgment and the ability to plan their actions.The basic principle Starting from the essential feature of intelligent manufacturing system in distributed manufacturing network environment, according to the basic idea of distributed integration,In the application of distributed artificial intelligence theory and method of multi Agent system, realize flexible manufacturing unit of the intelligent and flexible manufacturing system based on network intelligent integration. According to the characteristics of the distribution system of isomorphism in a local area forms for realizing intelligent manufacturing system based on the actual also reflects the internet-based global manufacturing the realization of the intelligent manufacturing system model under the network environment.The overall idea of distributed IMS network:IMS is the essential characteristics of the individual manufacturing unit of autonomy and the system as a whole self-organizing ability, its basic pattern is distributed more intelligent system. Based on this understanding, and considering the internet-based global manufacturing network environment, we put forward the Agent based distributed IMS networks basic idea, as shown in figure 1. On the one hand, through the Agent give autonomy to each manufacturing unit, making it a fully functional, autonomy, an independent entity; On the other hand, through the coordination and cooperation between the Agent, gives system self-organization ability.Multi Agent system implementation pattern of the system is easy to design, implementation and maintenance, reduce the complexity of the system, enhance the systems restructuring, scalability and reliability, and improve the flexibility, adaptability and agility of the system. Based on the above framework, combined with the CNC machining system, development and application of distributed network prototype system by system manager, mission planning, design and producers of four nodes. Systems manager node including two database server, database server and Agent system is responsible for the management of the entire global database, available for access of nodes in the prototype system for data query, read, storage and retrieval operations, and for each node for data exchange and sharing, to provide a public system, the Agent is responsible for the system in the network and the external interaction, through the Web server on the Internet home page of the system, users can access online home page the information related to obtaining the system, and according to their own needs, to decide whether the system is to meet these requirements, the system of the Agent is also responsible for monitoring the interactions between the v
