<p>This special track focuses on the status of Japanese expert system development. It is composed of six articles, including this introductory overview. The second article by Funabashi, Maeda, Morooka, and Mori discusses fuzzy technology and its application to decision support and plant control expert systems. Developers usually adopt fuzzy technology for control systems, and there are many in operation. The third article by Sueda and Iwamasa also describes a plant control expert system, though this system uses model-based reasoning. These two articles provide a useful contrast of different approaches to the same task. These articles appear in this issue of IEEE Expert. The remaining articles will appear in upcoming issues.</p> <p>The fourth article by Yoshikawa, Kaneko, Ymanouchi, and Watanabe examines an expert system that makes time tables, a kind of scheduling expert system. The developers formulate this task as a constraint-satisfaction problem, devising and applying a new method for time table construction for high school classes. The fifth article by Takahashi and Matsumoto describes a case-based reasoning application to manufacturing process design. The authors discuss a commercial knowledge reuse-oriented shell named Kweshell and demonstrate that combining knowledge reuse and case-based reasoning makes it easier to solve real, large-scale problems. The sixth article deals with production planning; Hamada, Baba, Sato, and Yufu adopt a rule-based approach for the initial solution and a genetic algorithm for optimization. Table 1 summarizes the problems introduced by the articles and their respective problem-solving approaches.</p>
