Abstract
Using rough sets, we propose bike designs that match the image of works such as games and anime. Create a model by dividing the bike into parts, and then combine the parts to create a sample. The results of a questionnaire survey to find out what kind of image the created sample has will be analyzed using a rough set. Based on the analysis results, we propose a bike design based on the image by combining parts. In this research, it is possible to know the design of a motorcycle that matches the image of the work you want to create. Not only works where motorcycles are the main feature, but also works where motorcycles only appear as part of the background or in a certain scene, can be used to create the atmosphere of the work by using a motorcycle that fits the image.
