3D 선체모델을 이용한 블록 물류관제 시뮬레이션 연구

Abstract

In shipbuilding industry, spatial scheduling problem in the block assembly stage takes into account not only traditional scheduling constraints such as resource capacity and due dates, but also spatial layout of locating a 3D ship blocks in assembly process. The problem is very hard and time consuming because it should consider both scheduling and spatial arrangement of each block simultaneously. This spatial scheduling process has relied on expert workers. However there are several inefficiencies in the block shape extraction. For the automated spatial scheduling system, we propose new block 2D projection shape generation method based on a Tribon 3D ship structural model and general polygon clipping algorithm.
