摘　　要：目的利用排队论的相关知识,对医院中多服务台时两种排队模型进行分析比较。方法从医院信息系统(HIS)中提取有关排队数据,计算出平均到达率和平均服务率,运用排队论的数学模型,借助M/M/1模型和M/M/C模型的算法及有关辅助程序,得到评价指标。结果医院多服务台时,单一共享等待队列的性能显著优于多个独自的等待队列。结论在医院安排排队方式时,尽量采用单一共享等待队列。Objective To provide the theoretical evidence for queue management in a hospital by comparing the two waiting queue models at multiple servers. Methods Queue-related data were extracted the hospital information system（HIS）. Average arrival and service rate were calculated. Evaluation indexes were obtained using the queuing mathematical model and auxiliary algorithm program of M/M/1 and M/M/C model. Results The performance of a single waiting queue sharing more servers was significantly better than that of more waiting queues sharing one server. Conclusion A single waiting queue sharing more servers should be used in a hospital.
