Fuzzy Decision Tree Analysis to Investigate What Has an Influence on Ease-of-Use and Preference with Products - Making Up the Rules about Ease-of-Hitting and Preference of Golf Clubs

摘要

In recent years, a constructor is required to develop a product which is not only highly efficient and functional, but also attractive and easeful for users. It is difficult for constructors to investigate which part and element of product is closely related to attraction and ease-of-use with products. So we propose a method to investigate that relation with Fuzzy C4.5 decision tree. In this paper, we examined variation in sensitivity of player's hitting golf balls with variable golf clubs. They answered the feeling of hitting with a golf club with SD method and we got some rules to judge the ease-of-hitting and preference with golf club.
