Abstract： Aiming at improving the delivering drug speed of the rapid dispensing drug system，the movement of the delivering drug mechanism was investigated and a new method of delivering drug which is called electromagnet actions one by one was proposed. The mathematic models were built for the new method and the traditional method based on the delivering drug time，and then the models were simulated in Matlab by changing the parameters. At last，the data that collected from hospital was used in the models. The simulation results show that delivering time of the two methods is influenced by the maximum number of the medicine. The more the medicine need to deliver，the more time it costs；also，the delivering time of the traditional method is multiplied while the delivering time of the new method changed a little when the number of layers increased. The experimental results indicate that the new method can improve 47% efficiency over the traditional one.
