It has been an important issue to improve customers' satisfaction in theme parks for which become a major role of recreation in our daily life. Waiting for rides has been identified as a factor decreasing satisfaction. A previous study indicated that a virtual queuing system can reduce the total waiting time so the customer's satisfaction is improved. The results from a simulation tool Arena show that an index Satisfaction Value (SV) increases when the queuing system is introduced. In this study, a more complex scenario of theme park queuing system (TPQS) is first designed, followed by comparison of a number of combinations of the rides with various waiting time and distribution factors. Analysis is also carried out.

Facing the inevitable aging trend, Taiwan has implemented a long-term care program (LTC) to meet the demands of families with disabled seniors living at home. However, the medical resources currently provided by the local government, including physicians, nurses and physiotherapists that the shortage can reach 65%, 88% and 95%, has failed to catch up to the demands from the fast elderly growing population. The objective of this paper is to model the relationship of current disabled elderly at home and available medical resources by using linear programming. A multimedia data supported scenario and coordinated medical protocol have successfully provided the practical foundation of analysis in Taiwan. This study identifies the shortage of medical resources and provides optimal solution to shorten the difference under the cost concern is the number of (physician, nurse, and physiotherapists) to be (15, 27, and 22). This study excludes the local home care facilities for simplification purpose.
