Face Taiwan Medical system mechanism, in order to provide the best medication quality, approach cost efficiency without wasting any resources, and management goals of hospitals. Therefore, this paragraph based on Recurrent Neural Network to develop a time serial relation, to construct a formula to calculate the medication cost. According to the information we have, combined with the data base to analysis the current medical system, to understand the medical quality, cost efficiency, and problems. Once we understand the problems, we will be able to correct them and provide the best medical system(1987)6, with reduced cost. To be the guideline for the hospitals and reach our management goal.
