A METHOD TO REDUCE WAITING TIME FOR OUTPATIENTS IN A HOSPITAL BY QUEUING THEORY

摘要：

Queuing theory consists of two probability distributions. One is the arrival distribution and the other is the service distribution at the queue. A model should bedescribed with Kendall’s notation to solve problems in the model which is set to reduce waiting time of outpatients. In this paper, the queuing model is, firstly, searched by queuing theory for an outpatient department. Secondly, an assignment rule is proposed by queuing simula tions to reduce expected waiting time in waiting queues of outpatients. The rule is decided by four situations on the vacancy in outpatient department etc. , and the sequence in the waiting lines. Finally, effectiveness of the proposed rule is verified through numerical experiments.
