There are many restrictions on production in the factory. The most efficient production schedule should be planned taking
these restrictions into account. Professional skill is necessary to plan the best schedule. A schedule planner has to deal
with so much information during production planning that it is difficult to plan the best production schedule with a consideration
of so many restrictions. In this study we introduced the use of Petri nets to support such production planning with a computer.
Petri nets have been widely used to simulate production because of their capability of modeling concurrency, synchronization,
and sequencing in discrete-event systems. This paper reports on implementing a simulation system for the shipyard. We had
already implemented a production planning support system for a shipyard that is a part of the computer integrated manufacturing
(CIM) system in shipbuilding. Based on this system, we implemented a shipyard simulator that can simulate the production activity
in the shipyard. We therefore have defined a shipyard model. The production conditions can be changed, and the efficiency
of a schedule can be evaluated. This paper discusses the effectiveness of using a factory simulator.

This paper compares Chinese, Korean, and Japanese shipyard production technology. Development in the world shipbuilding over recent years has influenced focus areas related to shipyard manufacturing technologies and product performance. Software systems, information technology, production technology, and local challenges of shipyards are compared with shipbuilding outputs among these three countries. Various technologies developments, shipyard production and the problems in Chinese, Japanese, and Korean shipyards are discussed respectively. Finally, future areas of research are pointed out. 相似文献
