Shipbuilding is one of the most complex production systems in manufacturing industry because incredible variety parts and highly processes. However, plans are currently prepared manually depending on experience expert workers. In this paper, a planning method based shipbuilding process simulation proposed for use actual shipyards, which simultaneously satisfies needs both managers, who require ...

9 http://ammtiac.alionscience.com http://wstiac.alionscience.com BACKGROUND Modern US Navy ships use considerable quantities of piping to carry fresh water, ballast water, chilled water, wastewater and fuels throughout the ship. Traditionally, copper-nickel (90Cu-10Ni) alloy pipes have been used, but they are heavy, subject to both corrosion and moderate bio-fouling, and are expensive to procur...

Copyright ©1997, Technology Publishing Company process and its interaction with the other aspects of shipbuilding, namely steelwork and outfitting. As a result of the research programme, a technical association was set up at the end of 1996 between Appledore International and International Paint. The aim of this association is to combine the shipyard production and engineering expertise of the ...

A pattern recognition system is described for recognizing shipbuilding parts using artificial neural networks and Fourier descriptors. The system uses shape contour information that is invariant of size, translation, and rotation. Fourier descriptors provide information, and the neural networks make decisions about the shapes. A brief review of the current state of the art is included, and resu...

We introduce a method for approximating a given surface by a developable surface. It will be either a G surface consisting of pieces of cones or cylinders of revolution or a G NURBS developable surface. Our algorithm will also deal properly with the problems of reverse engineering and produce robust approximation of given scattered data. The presented technique can be applied in computer aided ...

Located in Guangxi Province, China, the Liuzhou Iron and Steel Company is one of China’s leading suppliers of plate steel to its shipbuilding industry. Also exporting to countries such as Japan, Germany, Singapore and Thailand, the company is now capable of producing one million tons of steel per year, owing to a series of recent technical innovation projects. Foremost among these is an ongoing...
