Re-building a new algorithm of the out-patient appointment system to reduce long waiting-time—a case study

In the recent years, as aging society becomes serious in Japan, people, especially those in the health industry, focus on the improvement of healthcare. Due to the unsuitable algorithm of out-patient appointment systems, patients always complain about long waiting-times. Because of this, it is necessary to re-build the algorithm of the out-patient appointment system to reduce waiting-times. In this paper, the current appointment method will be discussed, and the data of the current appointment system will be analyzed using statistic methods. By analyzing the result, a proposed appointment method and algorithm may be able to reduce the waiting-time.
