Abstract
The purpose of this paper is to describe the building of a members′ usage analysis system of a fitness club using Visual Basic and to apply this system to a fitness club located next to a major terminal station in the Tokyo metropolitan area.
The obtained data were in-out time records of the members of the club from April 2003 through March 2004, as well as its membership list. The daily usage data included date, clock-in time, clock-out time and membership number. The membership list included membership number, home address, type of membership, gender and age. The number of members for the club was over eight thousand. The annual cumulative number of users was approximately half a million. Monthly frequency in use for each member was calculated.
The findings of the analysis are summarized as follows :
1.The analysis system was proved to be effective in cleaning and sorting out the enormous quantity of usage data.
2.Much the same relationships approximated by exponential function were observed between frequency in usage and number of users for any month throughout the year.
3.The extremely high coefficient of determination indicated that the frequency in use and the number of users were highly correlated.
4.The linear expression model was statistically useful for the prediction of the number of users.
