基于排队论模型的医院MRI设备资源配置分析

MRI allocation analysis of regional hospitals based on queuing simulation model

目的：通过建立排队模型，研究华东某地区医院磁共振成像（MRI）设备资源配置情况。方法：采用统计学方法对MRI的检查时间进行统计，建立排队模型，分析7所医院MRI的配置使用情况，计算出等待队长、平均队长、逗留时间和等待时间等参数。结果：某地区内的7所医院MRI检查平均等待时间为0.403 h。其中2所医院的等待时间＞40 min；3所医院的等待时间＜20 min；2所医院的设备利用率较高，空闲率为11.9%-16.4%，2所医院的设备利用率较低，空闲率为52.3%-58.9%。结论：通过建立区域MRI检查中心并辐射周边区域，以解决设备资源配置不平衡的问题。

Objective：Setting up a queuing simulation model to study the allocation and usage of MRI in certain regional hospital in East China. To find out the causes and put forward suggestions. Methods： Statistical method was used for statistical analysis of MRI inspection time. Queuing simulation model was used to analyzing MRI allocation and used in 7 top hospitals. The waiting queue length, average queue length, sojourn time and waiting time was calculated.Results： The average MRI examination waiting time of the 7 top hospitals in the whole region is 0.403 h. The waiting time of 2 hospitals is more than 40 min while which is less than 20 min in 3 hospitals. The equipment utilization rate is higher in 2 hospitals （vacancy rate is 11.9%-16.4%） while which is lower in 2 other hospitals （vacancy rate is 52.3%-58.9%）.Conclusion： The problem of health allocations of resources could be solved by establishing regional MRI examination center radiation regional around.
