The line-heating method is applied to the bending work of hull steel plate. These processes have been dependent on skilled worker's hand-working based on mainly experience. However, it has become necessary to mechanize the line heating working and establish the forming technology, because the skilled workers have recently been decreased. In order to solve these problems, we have two approaches; one is to analyze physical phenomena theoretically, and the other is systematization of the skillful workers' knowledge. In this paper, an expert system of plate bending by line heating is developed. By interviewing skillful workers to construct production rules, an expert system is built on "Nexpert Object"; the knowledge base development system of Neuron Data Inc. The system is easy to maintain rules, and it has user-friendly interfaces. Its validity is examined through an application of the system to processing of actual plates in a shipyard.
