摘要
为了改善医院运作效率,减少患者就诊等待时间,我国三甲医院推行患者预约就诊,因此,需要确定患者预约挂号数量.构建有两类患者到达的(M_1+M_2)/M/1非抢占优先权的患者预约排队模型,利用母函数法给出该排队系统的稳态指标、排队模型的患者就诊成本函数以及最优预约患者数量.进一步,对排队模型相关参数进行灵敏度分析,得到模型参数对于最优预约量以及患者总就诊成本的影响.
In order to improve the efficiency of hospital medical operation and reduce the waiting time for patients,the implementation of patients＇ making an appointment in the three level hospitals.Thus,it＇s needed to determine the number of patients registered appointment.In this paper,we construct a（M1＋M2）/M/1queuing model with two types of patients＇ visiting with non-preemptive priority,using the method of probability generating function,to get the steady-state index of the queuing system,the patient cost function and the optimal number of appointments.The sensitivity of the relevant parameters of the queuing model is analyzed,and the influence of the model parameters for the optimal appointment capacity and the total cost of the registration is obtained.
