Research On The Key Techniques Of Intelligent Process Information System For Agile Enterprises

Computer Aided Process Planning (CAPP) is one of the nucleal techniques of advanced manufacturing,as well as the basic technique of Computer Integrated Manufacturing System(CIMS)% Concurrent Engineering(CE) and agile Manufacturing (AM). CAPP plays a very important role in enterprise informatization as the bridge between Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM). With the driving of advanced manufacturing techniques,such as agile manufacturing,network manufacturing,CAPP is developed for process information system with characters of process planning & management integrating,intelligent running,cooperating planning etc. In this dissertation,the architecture and key techniques of intelligent process information system for agile enterprises are described,theory and methodology of intelligent process information system software development have been founded. The dissertation has important theoretical value and practical significance. The key issues studied and conclusions deduced in the dissertation are as follows:1. Based on the analysis of the actuality and requirements of computer aided process planning and management for agile enterprises,the conclusion of that CAPP systems have to be developed with the characteristics of process planning and management integrating,intelligent running,cooperating planning has been conducted.2. The concept of intelligent process information system is improved and enriched. The architecture of intelligent process information systems,based on the combination of Internet techniques with distributed components for agile enterprises is studied firstly by the author in CAPP field. The architecture can be used to plan and develop intelligent process information systems. And the functions and composes of it is analyzed in detail also.3. An Object-Oriented process information modeling architecture,which is the basic theoretical foundation of process knowledge management,is founded. In order to manage process knowledge effectively,such works as determination of the source of process knowledge,modularization of process knowledge,forming of process knowledge map,foundation of process knowledge portal,planning and implement of process knowledge management system are described. The key techniques of planning,developing,implementing procedures of process knowledge management systems areanalyzed furthermore.4. Key techniques of agile and cooperative process planning in agile manufacturing environment are systematically analyzed. It is concluded as follows. The process standardization is the basis of implementing agile process planning. The man-machine hybrid intelligent process planning and Object-Oriented process decision-making are the means of implementing agile process planning. The process planning service provider provides the possibility of rapid process planning. And the Computer Supported Cooperative Work is the basis of cooperative process planning. In the dissertation,cooperative process planning based on distributed workflow,cooperative process planning team,cooperative manufacturing resource supporting,collision resolving strategy,concurrent and cooperative of product design and process planning are described as the key techniques of cooperative process planning systems.5.Efficient management of process data is the main method of improving process planning engineering's efficiency,at the same time,it's one of the difficult problems of process planning. Key problems,such as integrated product process data model,process planning based on integrated product process data model,single source of process data integrating and management are described. Ways and key techniques of product process data management,such as process planning version management and validity controlling,check-in and check-out of process data,retrieval and querying of process data,borrowing of process planning,all kinds of summing and stating,MBOM management etc. are described in detail.6.Based on analyzing of requirement in product process data integrating and describ...
