| 摘要： | In the modular construction of ships, significant productivity losses can occur during the erection stage, when the modules, or hull blocks, are joined together. Frequently, adjacent blocks do not fit together properly, and rework of one or both of the mating block interfaces is necessary to correct the problem. The specific cause of rework is the variation of plate edges at the block interface, which is itself a cumulative product of numerous manufacturing variations inherent in hull block construction. Variation in manufacturing is unavoidable, but not uncontrollable. The application of accuracy control technigues in shipbuilding has proven that a statistical analysis of variation makes possible an accurate prediction of its effects. This report presents an examination of block interface variation, and the subsequent development of a computer simulation method of predicting rework levels on those blocks. / NOTE:Paper no. 4. |
