It is needless to say that much information on process planning and scheduling is very important for production activities. There are various restrictions in the factory. The most efficient production schedule must be planned in consideration of those restrictions. However, information handled by production scheduling is huge and it is very difficult to plan the best schedule. Therefore, skill is needed for production scheduling. In this research, authors use the Petri Net that is suitable for modeling the parallel, asynchronous system, and the nondetermination event to support production scheduling with the computer simulator of a shipyard. We aimed to implement the factory simulation system of the shipbuilding. We have already implemented the production scheduling support system in the shipyard that is partially of our research in CIM for shipbuilding. In order to use this result of our research more, we implement the system that can evaluate the effectiveness of generated production schedule by the factory simulator. Time is freely controlled in the computer and we implement the shipyard simulation system that can simulate the process of the production activity in a shipyard. This paper shows the effectiveness of the use the factory simulator.
