摘　　要：目的探讨排队论模型在军队医院门诊超声科设备配置中的应用效果。方法运用现场调查法和排队论模型,计算超声科设备工作强度(ρ),患者排队等待人数(Lq),窗口逗留人数(Ls),平均排队等待时间(Wq),平均逗留时间(Ws),设备空闲概率(P0)患者到达必须等待的概率(P)等运行指标,并对应用排队论模型配置设备前后患者及技师进行满意度调查。结果超声科上下午分别配置6台和3台设备较为合理,在应用排队论模型配置设备后,技师和患者的满意度均得到明显提高(P<0.05)。结论利用排队论的方法可以较好地配置超声科设备,为提高服务效率提供科学参考。Objective To discuss the effect after the application of the queuing theory model in the configuration of ultrasound equipments in the military hospital. Methods Applying the on-site investigation and queuing theory model to calculate the intensity of ultrasound service （p）, the number of patients waiting in line （Lq）, the number of pa~ tients stay in queuing system （Ls）, the average waiting time （Wq）, the average length of stay （Ws）, MD idle probabili- ty （Po）, and the probability of queuing when patients arrived （F~, etc, and then making the satisfaction survey for physicians and patients. Results It was reasonable to configure 6 ultrasound equipments in the morning and 3 ultra- sound equipments in the afternoon, and the satisfaction of physicians and patients were both improved （P〈0.05）. Conclusion Utilizing the theory model could be useful to provide a basis for ultrasound equipments allocation, and to provide some scientific suggestions for improving medical service efficiency.
