The Analysis And Research Of Shipbuilding Coding System Based On Concurrent Engineering Model

The shipbuilding industry is a typical industry in which there are many kinds of products, little batch products, even produce a single product. The problem researched for a long time in shipbuilding industry is how to increase production efficiency, how to decrease production cost, how to shorten production period and how to improve benefits. Group technology was introduced into shipbuilding industry in late 1950 last century. Much work is done about technology alteration, developing new shipbuilding devices, ship design, manufacture management, reform shipbuilding system. And it is proved to be successful.With the fast development of technology, manufacture ways of shipbuilding industry are changing from dense labor force to dense devices and to dense information, and are developing towards the direction of dense knowledge. Ship-building companies try to apply related theories and methods of advanced manufacture technology, such as group technology(GT),single computer aid (CAD CAM CAPP) , concurrent engineering (CE), the theories and methods are used to direct design and produce, and realize modernization.Shipbuilding code is a very important basic work for modern shipbuilding, and it is also a produce organization form requirement, which is constantly developing with the development of shipbuilding model. In fact, shipbuilding code is a kind of a specified code regular which apply GT to classify information for shipbuilding procedure. When ship-building model is developing from traditional model based on subsection manufacture model to field manufacture model, the change of ship-building model enter into the second stage, that is to say, ship-building model should be directed by interim production and parted channels produce model, and it must establish the structure of code system directed by interim production and base on produce model.Some analysis and research on engineering decompose, shipbuilding, outfitting and painting are conducted through applying the related theories of CE in this paper, at the same time, ways and characters on design, production management and organization of modern ship-building under CE model are pointed. Ship code systemthat is fit to CE model is put forward, which is based on detail analysis of shipbuilding model. There is a particular introduce about the classification, system structure, system organization of shipbuilding code in chapter three.In the forth and the fifth chapter, theories about system engineering are applied to analyze and research shipbuilding code. Layer analysis method is used to do aided engineering decompose, and clustering analysis method is applied to aid classification for interim production. Meanwhile, analysis and research are conducted for the systems of shipbuilding code.In this paper, the research on shipbuilding code is based on particular analysis for shipbuilding model. It is valuable to apply the ideas and methods of CE and system engineering in analysis and research field for the research and development of shipbuilding code.
