The body-mind deterioration induced by speedy life style and working pressure is a common problem to the people in modern society. So it becomes more and more popular to take good care of one¡¦s health by exercising, which also promotes the development of professional sport and leisure business, for example, the aerobics club. But due to the economic depression, decrease in national income, and the impact of card debt, the operating conditions of many famous aerobic clubs are getting severe, even some of them close down. Therefore it is important to find the key success factors to manage aerobics clubs, so as to increase the probability of successful operation. The present study starts from collecting the relative references of sport and leisure business, aerobics, theory of decision-making management, and key success factors as well as their relative weighting. Then a Habitual Domains (HD) theory which is suitable to the characteristic of aerobics business is selected to analyze the key success factors. A multi-object decision-making method- Analytic Hierarchy Process (AHP) is also implemented to analyze the two questionnaires filled by professionals. Finally, the Expert Choice 2000 code is used to analyze the importance of key success factors and perform weighting calculation. Through the empirical analysis, the top priorities of key success factors of aerobics club operation are obtained, including the professionalism of coach, quality of service and software/hardware equipment. The operator of an aerobics club can follow the importance of priorities discussed in the present study to set up his own competitiveness, and then the aerobics club is assured to run permanently.

Abstract ¡§Taiwan Domestic Shipbuilding Industries and Warship Commercial Maintenance¡¨ is the long-term policy of defense independent industries pushed by the Taiwan government. Domestic shipbuilding, ship maintenance, and national integrated resources can be used to support naval ships logistic maintenance. But there are some differences in technology and concept between ¡§merchant ship¡¨ and ¡§warship¡¨. The complexity, mobility, and specialization of warship systems are higher than merchant ships. Every type of operating system now utilized by commercial shipyards must be modified if they want to receive and carry on warship commercial maintenance activity. Building desirable systems to conduct warship maintenance project management effectively is the key factor if commercial shipyards wish to carry on warship commercial maintenance activity. How to evaluate a warship commercial maintenance system and provide improved solutions for commercial shipyards is the main purpose of this research. This paper start from warship maintenance project management and focuses on warship commercial maintenance peculiarities to correct domestic public projects and shipbuilding related references. We use the Habitual Domains (HD) method to search Key Success Factors (KSF) for warships commercial maintenance system applied to commercial shipyards and to adopt Analytic Hierarchy Process (AHP) to exploit a multi-estimate criteria model to enhance effectiveness and reliability for evaluating a warship commercial maintenance system. The present study uses theoretical and actual experiences to develop a warship commercial maintenance system. Several recommendations are made in order to improve overall performance of a warship commercial maintenance system. We hope that domestic commercial shipyards can do the long-term planning and investment on conducting warship commercial maintenance activity. The navy also can perform warship maintenance frugally and diversely. In this way, navy and commercial shipyards can cooperate and realize the optimal benefit from both sides. ¡iKey Words¡j Taiwan Domestic Shipbuilding Industries, Warship Commercial Maintenance, warship maintenance project management, Habitual Domains (HD), Key Success Factor (KSF), Analytic Hierarchy Process (AHP)
