Sažetak

Pipes are the most significant ones of the components which constitutes the vessel body. Pipes are fabricated in piping plant at shipyard and exposed to some processes such as cutting, bending, hydrostatic tests, galvanizing and so on. Cutting operation is also vital process among the other ones since it is very crucial that the cutting surfaces are flat and the right angles. In shipyards, there are various pipe cutting methods such as plasma, oxygen, metal saw, band saw and abrasive cutting wheel. Shipyard production department desires to implement the most appropriate pipe cutting method in order to operate properly and effectively. The purpose of this study is to present the most convenient pipe cutting method according to the determined criteria. For this, fuzzy TOPSIS technique which is one of the most used fuzzy Multiple Criteria Decision Making (MCDM) methods in the literature is employed. The importance degrees of the criteria are evaluated by using fuzzy AHP. As a result of the presented study, the most appropriate pipe cutting method is determined for ship building industry.
