The Studying Theory And Application Of Concurrent Engineering

At present, the international economic competition is increasingly fierce, which is embodied in the competition of products. And its competition, in the final analysis, is the one of design and manufacture. The key to the competition is to bring the products to the market in the shortest time, at the best quality, at the lowest cost. As a new mode to develop the products, concurrent engineering combined the computer auxiliary design, manufacture, management and quality into one effectively so as to integrate and share the information and process.Some problems on concurrent engineering are illustrated in this dissertation, so the characteristics, systematic structures and technological keys of concurrent engineering are discussed; the basic features and application of applying tool on concurrent engineering are studied; the function of product data and managing technology in concurrent engineering is analysed; some important problems in the application of concurrent engineering is studied. By means of some cases, my own academic viewpoint and opinion are put forward meanwhile the definition of concurrent engineering is come up with.Propose the application of concurrent engineering in non-manufacture field,when studying the theory of concurrent engineering, the author is engaged in the theoretical application of concurrent engineering. Applied it to Liaoning Important Scientific Project"The Platform Building Of Scientific instrumental Equipment Co-system Based On Concurrent Engineering"in 2002 for the first time. On the grounds of its basic principle, the plan for implementation, re-organization of process and personnel is decided, the systematic structure and quota system ( mathematical model ) are set up. As a technological platform, the data bank and the corresponding data exchanging process are designed with all TRS data systematic management. And its research and implemental equipment are finished in the shorter time, the platform of scientific instrumental equipment co-system has been set up and the better results have been achieved. At present, the results have been applied in some departments in Liaoning Province and tested and appraised by the specialists of Scientific Department Of Liaoning Province. Fill in the blanks in this field of Liaoning province,the development of this project has made a great contribution to the building of scientific platform for our province.That the theory of concurrent engineering is used to the building of scientific instrumental equipment co-net expands its applying fields, enlarges its applying extension, fills in the blank of this field. To some extent, the theory of concurrent engineering is developed and its reform is put forward, which lays a solid foundation for the further research, reform and development of concurrent engineering.There are 7 chapters in this dissertation, its main contents as following:In the first chapter, the research background and the characteristics of modern manufacturing technology and its mode have been outlined; the origin of concurrent engineering and its development in both domestic and abroad and the fey point for present research have been discussed.In the second chapter according to the difference between the sequential engineering and concurrent engineering, the theory of concurrent engineering has been studied and analyzed from several parts, such as its working principle, technological key, systematic structure and characteristic.In the third chapter, the important point is the distribution of quality function and DFX in concurrent engineering. With some cases, the function of quality room and its applying principle have been explained.In the fourth chapter, the systematic structure about product data managing technology, its function and its relationship with the concurrent engineering have been introduced.In the fifth chapter, from the implementation of concurrent engineering, its implementing process, its form, the re-organization of development process of its objects and the coordination of its conflict have been discussed. How to project the plan of the scientific instrumental co-net based on concurrent engineering has been introduced.In the sixth chapter, the design of scientific instrumental co-net has been introduced.In the seventh chapter, on the research and practice of the theory of concurrent engineering, my own research conclusion has been drawn and some suggestions about its further study have been put forward.
