Abstract
This study deals with the management optimization and risk evaluation for gaming shops by considering about profit or loss from gaming and simulations. And it is investigated that this gaming model structures are based on systems reliability theoretical approach. Although there are multi kinds of many games or these shops about their gaming or simulations all over the world, in this study it is treated to use the behaviors about the variance spreading of gaming simulations based on each probabilistic phenomenon from view points of the service by the gaming supplier and the life cycle for its players. In addition it is examined that the characteristics of these estimations of maximum risk with gain by winner among players. Moreover, it is able to be suggested that the design optimization method about loss or risk throughout gaming simulation.
