To achieve information integration in manufacture process , this paper , with reference to dnc , researches into manufacture process information integration from 3 aspects : data level , function level , application level , presents the management information integration framework （ miif ） based on distributed control technology , builds meta - agent and application agent by regarding agent as an entity having special behavior ability and specific action objective , establishes agent control model , and then gives the collaborative solution . with field - bus technology and agent technology , the dnc system model based on agent technology is established which shows a efficient way of device integration . a general model of device integration is set up , and an agent model based on soft plug - in technology is built 该模式包括面向制造过程的车间生产管理与控制的上层结构和面向车间设备的加工控制的下层结构；为实现制造过程信息的集成，本文从三个层面：数据层面、功能层面、应用层面上阐述了车间制造过程信息的集成方式，并借鉴dnc思想，建立了基于分布式控制技术的制造过程信息集成框架（ miif ） ；采用面向对象方法，对miif中的代理体从定义抽象、结构和功能等进行了深入研究；从知识层面上的三个层次：语言规范、会话机制、问题域对miif的多agent协作进行研究，建立了多agent交互的形式化模型。
