Abstract :
In the production environment, there are many disruptions, such as machine breakdown, rush
orders, and so on. Under these circumstances, the shipyards have to meet customer demand. If this is not
done, the shipyard may face customer loss, since they cannot meet the deadline. So, it is very important
to understand the effects of machine breakdown on system throughput. In this study, the hull production
system of a shipyard situated in Turkey has been considered. In the first step of the study, the structure
of the double bottom block, which is produced in the shipyard production system, and the workstations,
which constitute the production system, were identified. Secondly, the simulation model of the production
system was created using simulation software. By creating some machine breakdowns for various work
stations in the production system, the effects of breakdown on system throughput have been investigated.
As a result of the study, the critical rates of machine breakdown, which have affected system throughput,
have been determined. The main contribution of the study is to allow production engineers to take
measures against machine breakdowns in advance, so that target throughput can be reached.
