In order to fair up surfaces on superstructure of ships, gas heating method is mainly applied. Such fairing prosesses have been dependent on skilled worker's hand-working based on mainly experience. Because skilled workers have recently been decreased, it has become necessary to systematize their knowledge. In this paper, an expert system of fairing work by gas heating is developed. By interviewing skillful workers to construct production rules, an expert system is built on "Nexpert Object", which is a knowledge base development system. It is easy to maintain rules of the system, and the system has user-friendly interfaces. Through an application of system to actual fairing work in a shipyard, the validity of the system is examined.
