我们研究了当部分患者患有传染病需要隔离时，医院病房的最优配置，包括私人病房和半私人病房。我们假设需求是随机的和季节性的。我们提出了一种基于随机规划的计算高效的求解过程，该过程使用不同接纳策略下的系统性能的渐近逼近，并证明了其在大型系统中的准确性。使用我们的模型，我们研究了医院设计中要求100%私人房间的最新趋势的适宜性。我们表明，即使是在隔离患者中，这种极端的做法也可能导致患者获得医院病床的机会大幅下降。
We study the optimal configuration of hospital inpatient rooms with private and semiprivate rooms when some of the patients have infectious diseases and need to be isolated. We assume that the demand is random and seasonal. We propose a computationally efficient solution procedure that is based on a stochastic program that uses asymptotic approximations for the system performance under different admission policies and show its accuracy for large systems. Using our model, we study the appropriateness of the recent trends in hospital design calling for 100% private rooms. We show that even with isolation patients such an extreme approach could result in a significant degradation in the access of patients to hospital beds.
