But recently, many people have a feeling of anxiety about several problems such as a fire and air pollution. Thus, the purpose of this paper is to propose a method which can improve the customer satisfaction. There are lots of positive and negative factors that influence people. To understand and analyze these factors, we conducted a questionnaire survey of people who usually use subway. From the obtained data, principle component analysis and K-means clustering method were implemented. Finally, for customer satisfaction, the factors which are needed to be concerned or solved are identified using cross-tabulation.
