A new design method for a traversal track formation in the linear-motor (LIM) driven transportation system has beeen developed. The object of the design is to minimize the LIM number assuring smoothness of vehicle speed control along the whole track. Conventionally, the design was made by human experts based on their experiments. Therefore, the quality of the design depends on their expert skill. To automate and standardize the design procedure, Cased Based Reasoning (CBR) technology was applied. In addition, Genetic Algorithms were used to update the CBR.
