基于特征的多代理分布式工艺规划方法

制造企业从大规模化转向了小型化 ,其中定单的处理是少量的并且时刻发生变化 .这种趋势导致虚拟车间的出现 ,虚拟车间包括一些分布在车间中的加工中心 .阐述了一些基本的概念和方法 ,用代理关联结构和特征继承关系来解决分布式工艺规划中的特殊问题 .在应用中 ,工艺规划的零件模型的特征继承性是关键 ,它有助于选择正确的机床和刀具 .

分布式CAPP中的多智能体协作研究

异地分布的企业和部门要求现代CAPP是一个多用户、多任务、分布、并行协同的工作环境,而多智能体技术作为支持该系统环境的重要研究和实现手段,其关键点及难点是使各智能体协同工作。本文在充分研究多智能体协作模型的基础上,采用基于黑板结构的协作机制,并结合实例,分析了分布式CAPP中智能体的协作运算过程,从而使CAPP中异地、异工种规划单元之间达到并行协作的目的。

Process Planning and Scheduling Integration in an Open Manufacturing Environment

New open manufacturing environments have been proposed aiming at realizing more flexible distributed manufacturing paradigms,which can deal with not only dynamic changes in volume and variety of products,but also changes of machining equipments,dispersals of processing locations,and also with unscheduled disruptions.This research is to develop an integrated process planning and scheduling system,which is suited to this open,dynamic,distributed manufacturing environment.Multi-agent system(MAS)approaches are used for integration of manufacturing processing planning and scheduling in an open distributed manufacturing environment,in which process planning can be adjusted dynamically and manufacturing resources can increase/decrease according to the requirements.One kind of multi-level dynamic negotiated approaches to process planning and scheduling is presented for the integration of manufacturing process planning and scheduling.
