In the presence of different service times of regular patients and nonpreemptive priority of emergency patients at the same day, this paper considers an advance appointment-scheduling problem of medical resources in which a finite amount of same-day service capacity should be allocated to different patients. This booking problem is modeled as a dynamic programming (DP) problem. The structural properties of DP model analytically reveal a booking limit policy. The booking limit numbers of regular patients do not monotonically increase with their revenues because of the service time differences. A numerical analysis is provided to test the performance of our booking limit policy by comparing polices in previous studies. Simulation results show that our policy provides a positive improvement in terms of the total reward of the service system, even when patients do not have perfect adherence to appointments (e.g., patient no-shows and unpunctuality). The numerical experiments demonstrate that the dedicated medical resource cannot improve emergency patients’ access to service but deteriorated their direct waiting time.

具有服务时间差异和紧急非抢占优先权的CT部门的容量管理

在普通患者的服务时间不同且急诊患者在同一天没有优先处理的情况下,本文考虑了医疗资源的提前预约计划问题,其中应为不同的患者分配有限数量的当日服务能力。此预订问题被建模为动态编程(DP)问题。DP模型的结构特性从分析上揭示了预订限制政策。由于服务时间的差异,普通患者的预约限度数不会随收入的增加而单调增加。通过比较以前的研究中的策略,提供了数值分析来测试我们的预订限制政策的效果。仿真结果表明,我们的政策在服务系统的总奖励方面提供了积极的改进,即使患者没有完全遵守约定(例如,患者未出现病情和守时)。数值实验表明,专用的医疗资源无法改善急诊患者的服务水平,但会增加他们的直接等待时间。
