Investigation of Single Section Part Fabrication in Shipbuilding by Utilizing Simulation Environment

Profil hazırlama, tersanedeki en önemli işlemlerden biridir. Profil işleme ünitesinde belirli boyutlara sahip profiller hazırlanmaktadır. Bu ünitede gecikme olduğunda, geminin teslim tarihi de gecikebilmektedir. Bu tip problemleri önlemek için profil işleme ünitesinin performansının yeterli olması gerekmektedir. Bu çalışmada bir tersanenin profil kesim ünitesi ele alınmış ve bu ünitenin performans analizi yapılmıştır. Çalışmanın ilk kısmında, profil işleme ünitesinin süreç analizi yapılmış ve simülasyon modeli oluşturulmuştur. Sonrasında, birtakım senaryolar uygulanarak çeşitli sonuçlar elde edilmiş ve değerlendirilmiştir. Bu senaryolar değerlendirildiğinde, markalama-kesim aktiviteleri üzerinde yapılabilecek olan iyileştirmelerin profil üretim miktarını artırdığı, diğer taraftan kenar temizleme ve taşlama işlemleri üzerinde yapılacak olan iyileştirmelerin profil kesim iş ünitesinin çıktı miktarını çok az etkilediği görülmüştür

Profile preparing process is an important work unit at a shipyard. At this station, the specific dimensioned profiles are obtained. In the case of any delay in this work unit, the delivery date may be postponed. In order to preclude these problems, the profile work unit performance has to be satisfactory. In this study, a profile processing work unit of a Turkish Shipyard was considered and the performance analysis was performed by using a simulation software. At the first stage of the study, process analysis of the profile processing work unit was carried out and then the simulation model was created. After that, some scenarios were implemented. It was concluded from these scenarios that the improvements on the operation time of marking-cutting activities increase the production quantity of profile. On the other hand, the improvements on edge sweeping and grinding activities have a very little affect on throughput of profile cutting work unit
