Research On Key Technologies Of Digital Manufacturing Software Platform Based On Multi-Agent

Infomationlization is a trend in every field, manufacturing field is not an exception. The infomationlization of manufacruring is to implement product digital desining, digial manufacturing, digital producing management and digital consultiong and service, i.e. digial manufacturing. An issue present is how to intergrate distributed components with differenct function into a unique platform. Muti Agent system (MAS) provides the polibility to sove this problem.Multi Agent based digital manufacturing software platform theories and key technologies are focused. The new theories, new structures, new methods and new tecknologies are used to implement a multi Agent based software platform. The main contents are as below:(1) Multi Agent and multimedial based collaborated designing and conflict eliminating is researched. A collaborated designing soft MICAD (Multi Agent Intelligent Computer Aided Designing) platform is implemented by using the multi Agent technologhy. In the MICAD system, multimedia such as audio and video are intergrated which are often in different systems before that is hard to represent the real time changing. On different views, the conflicts in collaborated designing baed Agent are researched then a conflict eliminating model is created. In this model, several different function Agents are called to process the request in the designing then find a way to solve the conflict. If the conflict is hard to find a way to eliminate, then the multimedia system is used to solve the issue manually thoughtout audio/video conference.(2) The developing and related theories of CAPP (Computer aided process planning) and how to use the multi Agent technology in the CAPP are researched. A multi Agent based CAPP system are implemented.(3) The control ways, orgnization structure and comptetion and collaboration of shop floor are researched. Applied the muti Agent to shop floor optimize schedule swarm algorithm then designed a muti Agent based schedule model and implemented a shop floor schedule system on JADE (Java Agent Devloping Enviroment).(4) Using the Fusion method, the system alalysising method OOA (Object Oriented Analysising) and system desiging method OOD (Object Oriented Designing) are improved; a new software engineering mothod O-AOP (Object-Agent Oriented Analysising) is brought. With the O-AOP, a virtual shop floor is implemented. The system analysing and designing are introduced. The virtual shop floor includes producing plan assigning, producing resource orgnizating and producing moniting.
